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,
		Band	band
	)

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
band	band of the source

◆ SourcePixelled() [2/2]

template<typename T >

SourcePixelled::SourcePixelled	(	const PixelMap< T > &	gal_map,
		PosType	my_z,
		PosType	factor,
		PosType	my_zero_point,
		Band	band
	)

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.

The units of the input image are assumed to be in ergs/s/cm^2/Hz.

Parameters

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

Member Function Documentation

◆ SurfaceBrightness()

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

virtual

Surface brightness of source in grid coordinates not source centered coordinates.

The units shuld be ergs / s / Hz / cm^2
