scopesim_templates.extragalactic.galaxy(sed, z=0, amplitude=15, filter_curve='g', pixel_scale=0.1, r_eff=2.5, n=4, ellip=0.1, theta=0, extend=3, ra=10, dec=-10)

Create a source object of a galaxy described by its Sersic index and other parameters.

This function is ideal for imaging or simple spectroscopy.

Parameters:

sedstr or Spextrum

zfloat

redshift of the galaxy

r_efffloat

effective radius of the galaxy in arcsec, it accepts astropy.units

amplitudefloat

magnitude or flux of the galaxy, it accepts astropy.units

filter_curvestr

name of the filter where the magnitude refer to

pixel_scalefloat

the scale in arcsec/pixel of the instrument

nfloat

Sersic index of the galaxy

ellipfloat

ellipticity of the galaxy

thetafloat

position angle of the galaxy

extendfloat

Size of the image in units of r_eff

rafloat, str

RA of the source, default 10

decfloat, str

DEC of the source, default -10

Returns:

srcscopesim.Source
