get_porb_norm

cosmic.utils.get_porb_norm(Z, close_logP=4.0, wide_logP=6.0, binfrac_tot_solar=0.66, Z_sun=0.02)

Returns normalization constants to produce log normals consistent with Fig 19 of Moe+19 for the orbital period distribution

Parameters:

Zarray

metallicity values

close_logPfloat

divding line beween close and intermediate orbits

wide_logPfloat

dividing line between intermediate and wide orbits

binfrac_totfloat

integrated total binary fraction at solar metallicity

Returns:

norm_widefloat

normalization factor for kde for wide binaries

norm_closefloat

normalization factor for kde for wide binaries
