precess_times¶

sofia_redux.scan.coordinate_systems.epoch.precession_numba_functions.precess_times(p, ra, dec, cos_lat, sin_lat)[source]¶

Precess the coordinates with a precession matrix.

RA and DEC coordinates are updated in-place. Please see precess_single() for further details on the algorithm.

Parameters:

pnumpy.ndarray (float): The precession matrix of shape (shape, 3, 3)
ranumpy.ndarray (float): The Right Ascension coordinates in radians of shape (shape).
decnumpy.ndarray (float): The Declination coordinates in radians of shape (shape).
cos_latnumpy.ndarray (float): The cosine(latitude) values of the coordinates of shape (shape).
sin_latnumpy.ndarray (float): The sine(latitude) values of the coordinates of shape (shape).

Returns:
