	SourcePixelled (const PixelMap< T > &gal_map, PosType z, PosType factor, PosType zero_point)
	Creates a SourcePixelled from a PixelMap image. The idea is to use stamps of observed galaxies as input sources for simuations. Surface brightness of the source is conserved, taking into account the input pixel size. Factor allows for rescaling of the flux, in case one wants to simulate a different observation.

Detailed Description

Class for sources described by an array of pixels.

The sources are created as a square array of pixels of dimension Npixels x Npixels and pixel size equal to resolution.

Constructor & Destructor Documentation

SourcePixelled() [1/2]

SourcePixelled::SourcePixelled	(	PosType	my_z,
		PosType *	my_center,
		int	my_Npixels,
		PosType	my_resolution,
		PosType *	arr_val,
		PosType	zero_point )

Parameters

my_z	redshift of the source
my_center	center (in rad)
my_Npixels	number of pixels per side
my_resolution	resolution (in rad)
arr_val	array of pixel values (must be of size = Npixels*Npixels)
zero_point	magnitude zero point

SourcePixelled() [2/2]

template<typename T >

SourcePixelled::SourcePixelled	(	const PixelMap< T > &	gal_map,
		PosType	my_z,
		PosType	factor,
		PosType	zero_point )

Creates a SourcePixelled from a PixelMap image. The idea is to use stamps of observed galaxies as input sources for simuations. Surface brightness of the source is conserved, taking into account the input pixel size. Factor allows for rescaling of the flux, in case one wants to simulate a different observation.

Parameters

gal_map	Input image and information
my_z	redshift of the source
factor	optional rescaling factor for the flux
