grss.fit.fit_optical.debias_obs

grss.fit.fit_optical.debias_obs(r_asc_vals, dec_vals, epoch_vals, catalog, biasdf, nside)

Calculate the bias on an optical observation given the epoch and the star catalog.

Parameters:

• r_asc (float) – Right Ascension in radians.

• dec (float) – Declination in radians.

• epoch (float) – Epoch of observation in JD TT.

• catalog (str) – Star catalog MPC code.

• biasdf (pandas DataFrame) – Bias dataframe of MPC star catalogs.

• nside (int) – Healpix nside parameter.

Returns:

• ra_deb (float) – Debiased right ascension in radians.

• dec_deb (float) – Debiased declination in radians.
