Bases: synthpop.modules.post_processing._post_processing.PostProcessing

Postprocessing module to apply a correction to F146 extinction

Attributes

use_low_extinction = False

roman_filter_list = ['f062', 'f087', 'f106', 'f129', 'f158', 'f184', 'f213', 'f146']

static generic_extinction_polynomial(AKs_C, coeffs, order)

Generic polynomial function of flexible order. Any number of colors may be input, and cross-terms are computed between A_Ks and each color, not between different colors.

Identical function to that used to run the fits.

Parameters:

AKs_Cndarray

array of extinction and color values to compute extinction estimate

coeffsndarray

array of coefficients for the polynomial function

orderint

polynomial order for the extinction coefficient function

Returns:

ext_estsndarray

extinction estimates for each star in the AKs_C table

get_roman_extinction_sim(catalog)

Roman extinction estimator for simulations. Assumes all Roman filter photometry is provided and in absolute AB mags.

Parameters:

catalogpd.DataFrame, astropy.table.Table, or similar

required columns: A_Ks, f062, f087, f106, f129, f158, f184, f213, and f146

low_extinction=Falseboolean

if all A_Ks<=1, use the alternate lower order correction. if any A_Ks>1, a warning will be printed, and the higher order correction will be used

Returns:

extinctionsdict

entries of ‘<filter>’:[<ext_star1>, <ext_star2>, …] for each filter
