Detailed Description

Class for sources described by shapelets.

The sources are created from magnitude, scale radius, and the coefficients of their decomposition into the shapelets basis functions (Refregier et al., 2001). The coefficients can be read from a fits square array. In case the magnitude is not given as input, the constructor will read an array of values from the shapelet file header. One can then choose the desired magnitude with setActiveMag.

Constructor & Destructor Documentation

SourceShapelets() [1/3]

SourceShapelets::SourceShapelets	(	PosType	my_z,
		PosType	my_mag,

		PosType	my_mag,
		std::string	shap_file,
		PosType *	my_center,
		PosType	my_ang,
		PosType	zeropoint,
		Band	band )

Parameters

my_z	redshift of the source
my_mag	magnitude
shap_file	fits file with coefficients in a square array
my_center	center (in rad)
my_ang	rotation angle (in rad)
zeropoint	magnitude zero point

SourceShapelets() [3/3]

SourceShapelets::SourceShapelets	(	std::string	shap_file,
		PosType	my_ang,

Member Function Documentation

printSource()

void SourceShapelets::printSource ( )

virtual

Implements Source.

rotate()

void SourceShapelets::rotate ( PosType ang )

inline

rotate source

Parameters

ang	angle in radians

SurfaceBrightness()

PosType SourceShapelets::SurfaceBrightness ( const PosType * y ) const

virtual

Returns surface brightness in erg/cm2/sec/Hz, normalized by hplanck. Given the units of hplanck, the final units are 1/sec/cm2.

Implements Source.
