gdt.missions.fermi.gbm.localization.dol.legacy_functions.ang_to_cart_dec(ra, dec)[source]¶

Convert right ascension and declination to Cartesian coordinates.

Parameters:

ra (float32, np.ndarray(float32)) – Right ascension(s) in radians
dec (float32, np.ndarray(float32)) – Declination(s) in radians

Returns:

pos (np.ndarray(3, float32)) – X, Y, Z position vector(s)
