zdm.optical.get_pz_prior(grid, DM)[source]

Returns posterior redshift distributiuon for a given grid and DM magnitude distribution for FRBs of DM given a grid object

Parameters:

grid (class grid object) – grid object modelling p(z,DM)
DM (float or np.ndarray of floats) – FRB dispersion measure, pc cm^-3

Returns:

probability distribution in redshift space

Return type:

pz (np.ndarray)
