ska_ost_senscalc.low.sefd_lookup

class ska_ost_senscalc.low.sefd_lookup.SEFDTable(db_path=None)

Encapsulation of the SEFD lookup table to be used for SKA LOW calculations

lookup_stokes_i_sefd(az: float, el: float, start_lst: float, end_lst: float, freq_fine_mhz: ndarray) → ndarray

Look up the SEFD values from the database corresponding to the local coordinates (az, el) between LST start_lst and end_lst.

Returns:

an array of Stokes I SEFD values at frequencies in fine_freq_mhz.
