Detailed Description

Plasmoid Shere of plasma emitting synchrotron, following a trajectory specified in getVelocity (non-geodesic a priori)

Member Typedef Documentation

◆ Subcontractor_t

typedef Gyoto::SmartPointer<Gyoto::SmartPointee> Gyoto::SmartPointee::Subcontractor_t(Gyoto::FactoryMessenger *, std::vector< std::string > const &)

inherited

A subcontractor builds an object upon order from the Factory.

Various classes need to provide a subcontractor to be able to instantiate themselves upon order from the Factory. A subcontractor is a function (often a static member function) which accepts a pointer to a FactoryMessenger as unique parameter, communicates with the Factory using this messenger to read an XML description of the object to build, and returns this objet. SmartPointee::Subcontractor_t* is just generic enough a typedef to cast to and from other subcontractor types: Astrobj::Subcontractor_t, Metric::Subcontractor_t, Spectrum::Subcontractor_t. A subcontractor needs to be registered using the relevant Register() function: Astrobj::Register(), Metric::Register(), Spectrum::Register().

Constructor & Destructor Documentation

◆ Plasmoid()

Gyoto::Astrobj::Plasmoid::Plasmoid ( )

Default constructor.

Create Plasmoid object with undefined initial conditions. One needs to set the coordinate system, the metric, the type of motion, and the initial position and velocity before integrating the orbit. initCoord() can be used for that.

Member Function Documentation

◆ deltaInObj()

double Gyoto::Astrobj::Standard::deltaInObj ( ) const

inherited

Get Generic::delta_inobj_.

Get the constant integration step inside the astrobj

Returns: delta_inobj_ in geometrical units

◆ deltaMax() [1/2]

virtual double Gyoto::Astrobj::UniformSphere::deltaMax ( double * coord )

virtualinherited

Parameters

[in] coord current photon position

Returns: max( dltmor_*radius_, dltmod_*operator()(double coord[]) )

◆ deltaMax() [2/2]

virtual double Gyoto::Astrobj::Generic::deltaMax ( double coord[8] )

virtualinherited

Get max step constraint for adaptive integration.

Parameters

[in] coord position

Returns: max step to find this object reliably

Reimplemented in Gyoto::Astrobj::Complex.

◆ describeProperty()

std::string Gyoto::Object::describeProperty ( Gyoto::Property const & p ) const

inherited

Format desrciption for a property.

Returns a string containing the name(s) and type of the property, as well as whether it supports unit.

◆ emission()

virtual void Gyoto::Astrobj::Generic::emission	(	double	Inu[],
		double const	nu_em[],
		size_t	nbnu,
		double	dsem,
		state_t const &	coord_ph,
		double const	coord_obj[8] = `NULL`
	)		const

virtualinherited

Specific intensity I_ν for several values of ν_em

Called by the default implementation for processHitQuantities().

emission() computes the intensity I_ν emitted by the small volume of length dsem. It should take self-absorption along dsem into account.

Same as emission(double nu_em, double dsem, double coord_ph[8], double coord_obj[8]=NULL) const looping on several values of nu_em.

Parameters

Inu[nbnu]	Output (must be set to a previously allocated array of doubles)
nu_em[nbnu]	Frequencies at emission
nbnu	Size of Inu[] and nu_em[]
dsem	Length over which to integrate inside the object
coord_ph	Photon coordinate
coord_obj	Emitter coordinate at current photon position

Returns: I_ν or dI_ν [W m-2 sr-2]

Reimplemented in Gyoto::Astrobj::Python::ThinDisk, and Gyoto::Astrobj::Python::Standard.

◆ fillElement()

virtual void Gyoto::Object::fillElement ( Gyoto::FactoryMessenger * fmp ) const

virtualinherited

Fill the XML element for this Object.

The base implementation simply calls fillProperty() for each Property defined for the Object.

Derived classes should avoid overriding fillElement(). It may make sense occasionally, e.g. to make sure that the metric is output first.

To customize how a given Property is rendered, it is better to override fillProperty().

If this method is overridden, the implementation should in general call fillElement() on the direct base.

Reimplemented in Gyoto::Scenery, Gyoto::Spectrometer::Complex, Gyoto::Astrobj::Complex, and Gyoto::Metric::Complex.

◆ fillProperty()

virtual void Gyoto::Object::fillProperty	(	Gyoto::FactoryMessenger *	fmp,
		Property const &	p
	)		const

virtualinherited

Output a single Property to XML.

The base implementation decides what to do based on the p.type. The format matches how setParameters() an setParameter() would interpret the XML descition.

Overriding this method should be avoided, but makes sense in some cases (for instance Screen::fillProperty() selects a different unit for Distance based on its magnitude, so that stellar sizes are expressed in solar radii while smaller sizes can be expressed in meters and larger sizes in parsecs).

Overriding implementation should fall-back on calling the implementation in the direct parent class:

class A: public Object {};
class B: public A { 
 using B::setParameter;
 virtual void fillProperty(Gyoto::FactoryMessenger *fmp,
                        Property const &p) const ;
};
void B::fillProperty(Gyoto::FactoryMessenger *fmp,
                        Property const &p) const {
  if (name=="Duff") fmp->doSomething();
  else A::fillProperty(fmp, p);
}

Reimplemented in Gyoto::Screen, Gyoto::Scenery, Gyoto::Astrobj::Star, Gyoto::Spectrometer::Uniform, Gyoto::Astrobj::PolishDoughnut, Gyoto::Astrobj::Disk3D, Gyoto::Astrobj::PatternDisk, Gyoto::Astrobj::DirectionalDisk, Gyoto::Astrobj::DynamicalDisk, Gyoto::Astrobj::EquatorialHotSpot, Gyoto::Astrobj::XillverReflection, Gyoto::Metric::Shift, and Gyoto::Astrobj::NeutronStarModelAtmosphere.

◆ fitsClose()

fptr	fitsfile pointer to FITS file to be closed

◆ fitsCreate()

fitsfile* Gyoto::FitsRW::fitsCreate ( std::string filename )

inherited

Opens a new fits file referred to by a fitsfile pointer and fills the primary HDU by a single pixel equal to 0. Returns the fitsfile pointer to the new FITS file.

Parameters

filename Name of fits file to be created

◆ fitsWriteHDU()

void Gyoto::FitsRW::fitsWriteHDU	(	fitsfile *	fptr,
		std::string	extname,

	)

inherited

Writes specific HDU in FITS files.

Parameters

fptr	fitsfile pointer to FITS file
extname	Name of extension to be written

◆ getCartesian()

void Gyoto::Astrobj::Plasmoid::getCartesian	(	double const *const	dates,
		size_t const	n_dates,
		double *const	x,
		double *const	y,
		double *const	z,
		double *const	xprime = `NULL`,
		double *const	yprime = `NULL`,
		double *const	zprime = `NULL`
	)

virtual

Yield the Cartesian coordinates of the center of the sphere.

Implements Gyoto::Astrobj::UniformSphere.

◆ getDefaultQuantities()

virtual Gyoto::Quantity_t Gyoto::Astrobj::Generic::getDefaultQuantities ( )

virtualinherited

Which quantities to compute if know was requested.

Return a Gyoto::Quantity_t suitable as input to Gyoto::Scenery::setRequestedQuantities() to set de default quantities to compute for this object. The default of these defaults GYOTO_QUANTITY_INTENSITY.

Reimplemented in Gyoto::Astrobj::PageThorneDisk.

◆ getProperties()

virtual Property const* Gyoto::Astrobj::Plasmoid::getProperties ( ) const

virtual

Get list of properties.

This method is declared automatically by the GYOTO_OBJECT macro and defined automatically by the GYOTO_PROPERTY_END macro.

Reimplemented from Gyoto::Astrobj::UniformSphere.

◆ giveDelta()

virtual double Gyoto::Astrobj::Standard::giveDelta ( double coord[8] )

virtualinherited

Maximum δ inside object.

Gives the requested integration step δ_t (in coordinate time t) between two neighbooring points along a portion of geodesic inside an astrobj; the current implementation only considers a constant delta, equal to Standard::deltaInobj()

Parameters

coord input coordinate at which δ_t is given

Reimplemented in Gyoto::Astrobj::Python::Standard.

◆ help()

void Gyoto::Object::help ( ) const

inherited

Print (to stdout) some help on this class.

Describe all properties that this instance supports.

◆ Impact()

int Gyoto::Astrobj::Plasmoid::Impact	(	Gyoto::Photon *	ph,
		size_t	index,
		Astrobj::Properties *	data = `NULL`
	)

virtual

Does a photon at these coordinates impact the object?

Impact() checks whether a Photon impacts the object between two integration steps of the photon's trajectory (those two steps are photon->getCoord(index, coord1) and photon->getCoord(index+1, coord2)). Impact returns 1 if the photon impacts the object between these two steps, else 0. In many cases of geometrically thick obects, the implementation Astrobj::Standard::Impact() will be fine.

Impact will call Generic::processHitQuantities() (which is virtual and may be re-implemented) to compute observable properties on demand: if the data pointer is non-NULL, the object will look in it for pointers to properties which apply to its kind. If a pointer to a property known to this object is present, then the property is computed and store at the pointed-to address. For instance, all objects know the "intensity" property. If data->intensity != NULL, the instensity is computed and stored in *data->intensity.

If data is non-NULL and only in this case, processHitQuantities() will also call ph->transmit() to update the transmissions of the Photon (see Photon::transmit(size_t, double)). This must not be done if data is NULL (see Astrobj::Complex::Impact() for an explanation).

Impact() may not extend the ph Worldline. The only two dates that are guaranteed to be defined are at indices index and index+1.

Parameters

ph	Gyoto::Photon aimed at the object;
index	Index of the last photon step;
data	Pointer to a structure to hold the observables at impact.

Returns: 1 if impact, 0 if not.

Reimplemented from Gyoto::Astrobj::Standard.

◆ integrateEmission() [1/2]

virtual double Gyoto::Astrobj::Generic::integrateEmission	(	double	nu1,
		double	nu2,
		double	dsem,
		state_t const &	c_ph,
		double const	c_obj[8] = `NULL`
	)		const

virtualinherited

∫_ν₁^ν₂ I_ν dν (or j_ν)

Compute the integral of emission() from ν₁ to ν₂. The default implementation is a numerical integrator which works well enough and is reasonably fast if emission() is a smooth function (i.e. no emission or absorption lines). If possible, it is wise to implement an analytical solution. It is used by processHitQuantities to compute the "BinSpectrum" quantity which is the most physical: it is the only quantity that can be actually measured directly by a real-life instrument.

Reimplemented in Gyoto::Astrobj::Python::ThinDisk, Gyoto::Astrobj::Python::Standard, and Gyoto::Astrobj::Torus.

◆ integrateEmission() [2/2]

virtual void Gyoto::Astrobj::Generic::integrateEmission	(	double *	I,
		double const *	boundaries,
		size_t const *	chaninds,
		size_t	nbnu,
		double	dsem,
		state_t const &	cph,
		double const *	co
	)		const

virtualinherited

∫_ν₁^ν₂ I_ν dν (or j_ν)

Like double integrateEmission(double nu1, double nu2, double dsem, double c_ph[8], double c_obj[8]) const for each Spectrometer channel.

Reimplemented in Gyoto::Astrobj::Python::ThinDisk, Gyoto::Astrobj::Python::Standard, and Gyoto::Astrobj::PolishDoughnut.

◆ isThreadSafe()

virtual bool Gyoto::Object::isThreadSafe ( ) const

virtualinherited

Whether this class is thread-safe.

Return True if this object is thread-safe, i.e. if an instance and its clone can be used in parallel threads (in the context of Scenery::raytrace()). Known objects which are not thread-safe include Lorene metrics and everything from the Python plug-in.

The default implementation considers that the class itself is thread safe and recurses into the declared properties to check whether they are safe too. Classes that abide to the Object/Property paradigm and are themselves thread-safe have nothing special to do.

Objects that clone children in their copy constructor that are not declared as properties must take these children into account.

Classes that are never thread-safe must declare it. It acn be easily done using GYOTO_OBJECT_THREAD_SAFETY in the class declaration and GYOTO_PROPERTY_THREAD_UNSAFE in the class definition.

◆ operator()()

virtual double Gyoto::Astrobj::UniformSphere::operator() ( double const coord[4] )

virtualinherited

Square distance to the center of the sphere.

Ensure integration does not miss the object

Implements Gyoto::Astrobj::Standard.

Reimplemented in Gyoto::Astrobj::StarTrace.

◆ opticallyThin() [1/2]

void Gyoto::Astrobj::Generic::opticallyThin ( bool flag )

inherited

Set whether the object is optically thin.

Set flag indicating that radiative transfer should be integrated, i.e. the object is to be considered optically thin.

Parameters

flag	1 if optically thin, 0 if optically thick.

◆ opticallyThin() [2/2]

bool Gyoto::Astrobj::Generic::opticallyThin ( ) const

inherited

Query whether object is optically thin.

See opticallyThin(bool flag).

◆ processHitQuantities()

virtual void Gyoto::Astrobj::Generic::processHitQuantities	(	Photon *	ph,
		state_t const &	coord_ph_hit,
		double const *	coord_obj_hit,
		double	dt,
		Astrobj::Properties *	data
	)		const

virtualinherited

Fills Astrobj::Properties.

processHitQuantities fills the requested data in Impact. To use it, you need to call it in the Impact() method for your object in case of hit. It will fill Redshift, Intensity, Spectrum, BinSpectrum and update the Photon's transmission by calling Photon::transmit(), only if data==NULL.

You can overload it for your Astrobj. The generic implementation calls emission(), integrateEmission() and transmission() below.

Reimplemented in Gyoto::Astrobj::PageThorneDisk, Gyoto::Astrobj::ThinDiskProfile, and Gyoto::Astrobj::DynamicalDiskBolometric.

◆ property()

Property const* Gyoto::Object::property ( std::string const pname ) const

inherited

Find property by name.

Look into the Property list for a Property whose name (or name_false, for a boolean Property) is pname. Return a const pointer to the first such property found, or NULL if none is found.

◆ rMax() [1/4]

virtual double Gyoto::Astrobj::Generic::rMax ( )

virtualinherited

Get maximal distance from center of coordinate system.

Get maximal distance from center of coordinate system at which a Photon may hit the object.

Child classes may use the rmax_ member to cache this value, if its current value is DBL_MAX.

It can also be set using rMax().

Returns: rmax_ in geometrical units

Reimplemented in Gyoto::Astrobj::Star, Gyoto::Astrobj::Torus, Gyoto::Astrobj::Complex, and Gyoto::Astrobj::FixedStar.

virtual void Gyoto::Astrobj::Generic::rMax ( double val )

virtualinherited

Set maximal distance from center of coordinate system.

Set maximal distance from center of coordinate system at which a Photon may hit the object.

Parameters

val	new rmax_ in geometrical units.

◆ rMax() [4/4]

virtual void Gyoto::Astrobj::Generic::rMax	(	double	val,
		std::string const &	unit
	)

virtualinherited

Set maximal distance from center of coordinate system.

Call Generic::rMax(double val) after converting val from unit to geometrical units.

Parameters

val	rmax_ expressed in unit "unit";
unit	string...

◆ setParameter() [1/2]

virtual int Gyoto::Object::setParameter	(	std::string	name,
		std::string	content,
		std::string	unit
	)

virtualinherited

Set parameter by name.

This function is used when parsing an XML description, if no Property of this name is found. Overriding implementation should fall-back on calling the direct's parent implementation:

class A: public Object {};
class B: public A { 
 using B::setParameter;
 virtual int setParameter(std::string name,
                    std::string content,
                    std::string unit);
};
int B::setParameter(std::string name,
                    std::string content,
                    std::string unit) {
  if (name=="Duff") doSomething(content, unit);
  else return A::setParameter(name, content, unit);
  return 0;  // name was known
}

Parameters

name	XML name of the parameter (XML entity). This may have a path component, e.g. "Astrobj::Radius", in which case a property named "Astrobj" will be sought in the current object, and setParameter will be called recusrively on this Astrobj with Radius as name.
content	string representation of the value
unit	string representation of the unit

Returns: 0 if this parameter is known, 1 if it is not.

Reimplemented in Gyoto::Astrobj::Star, Gyoto::Metric::RotStar3_1, Gyoto::Metric::KerrKS, and Gyoto::Astrobj::EquatorialHotSpot.

◆ setParameter() [2/2]

virtual void Gyoto::Object::setParameter	(	Gyoto::Property const &	p,
		std::string const &	name,
		std::string const &	content,
		std::string const &	unit
	)

virtualinherited

Set parameter by Property (and name)

This function is used when parsing an XML description, if Property (p) of this name is found (i.e. either p.name or p.name_false is equal to name). Implementation should fall-back on calling the direct's parent implementation:

class A: public Object {};
class B: public A { 
 using B::setParameter;
 virtual void setParameter(Gyoto::Property const &p,
                           std::string name,
                        std::string content,
                        std::string unit);
};
void B::setParameter(Gyoto::Property const &p,
                          std::string name,
                  std::string content,
                  std::string unit) {
  if (name=="Duff") doSomething(content, unit);
  else A::setParameter(p, name, content, unit);
}

Parameters

p	Property that matches name (p.name == name or p.name_false == name)
name	XML name of the parameter (XML entity)
content	string representation of the value
unit	string representation of the unit

Reimplemented in Gyoto::Astrobj::PolishDoughnut.

◆ setParameters()

virtual void Gyoto::Astrobj::Generic::setParameters ( FactoryMessenger * fmp )

virtualinherited

Main loop in Subcontractor_t function.

The Subcontractor_t function for each Astrobj kind should look somewhat like this (templated as Gyoto::Astrobj::Subcontractor<MyKind>):

SmartPointer<Astrobj::Generic>
Gyoto::Astrobj::MyKind::Subcontractor(FactoryMessenger* fmp) {
  SmartPointer<MyKind> ao = new MyKind();
  ao -> setParameters(fmp);
  return ao;
}

Each object kind should implement setParameter(string name, string content, string unit) to interpret the individual XML elements. setParameters() can be overloaded in case the specific Astrobj class needs low level access to the FactoryMessenger. See UniformSphere::setParameters().

Reimplemented from Gyoto::Object.

Reimplemented in Gyoto::Astrobj::Star, Gyoto::Astrobj::Complex, Gyoto::Astrobj::OscilTorus, and Gyoto::Astrobj::EquatorialHotSpot.

◆ transmission()

virtual double Gyoto::Astrobj::Generic::transmission	(	double	nuem,
		double	dsem,
		state_t const &	coord_ph,
		double const	coord_obj[8]
	)		const

virtualinherited

Transmission: exp( α_ν * ds_em )

transmission() computes the transmission of this fluid element or 0 if optically thick. The default implementation returns 1. (no attenuation) if optically thin, 0. if optically thick.

Parameters

nuem	frequency in the fluid's frame
coord	Photon coordinate
dsem	geometrical length in geometrical units

Reimplemented in Gyoto::Astrobj::PatternDisk, and Gyoto::Astrobj::DynamicalDisk3D.

◆ plugins_

std::vector<std::string> Gyoto::Object::plugins_

protectedinherited

The plug-ins that needs to be loaded to access this instance's class.

E.g. for an Astrobj, fillElement() will ensure

is written.

◆ rmax_

double Gyoto::Astrobj::Generic::rmax_

protectedinherited

Maximum distance to the center of the coordinate system [geometrical units].

Maximum distance from the center of the coordinate system at which a photon may hit the object. Child classes may compute a decent value for rmax_ at any time if rmax_ is DBL_MAX. External classes (Photons in particular) must use rMax() to access this information.

rmax_ is in geometrical units.
