stellar_mags

rubin_sim.utils.stellar_mags(stellar_type, rmag=19.0)

Calculates the expected magnitudes in LSST filters for a typical star of the given spectral type.

Based on mapping of Kuruz models to spectral types here: http://www.stsci.edu/hst/observatory/crds/k93models.html

Parameters:

stellar_typestr

Spectral type of a star (O,B,A,F,G,K,M), or for white dwarf colors, one of ‘HeWD_25200_80, ‘WD_11000_85’, ‘WD_3000_85’

rmagfloat

The expected r-band magnitude of the star.

Returns:

dict of floats

The expected magnitudes in LSST filters.
