sbm.SignalFields.diff_gain_field

static SignalFields.diff_gain_field(scan_field, mdim: int, gain_T: float, gain_B: float, temp_map: ndarray, pol_map: ndarray)

Get the differential gain field of the detector

Parameters:

• scan_field (ScanFields) – scan field instance

• mdim (int) – dimension of the map-making liner system

• gain_T (float) – gain of the Top detector

• gain_B (float) – gain of the Bottom detector

• temp_map (np.ndarray) – temperature map

• pol_map (np.ndarray) – polarization map (i.e. Q+iU)

Returns:

differential gain field of the detector

Return type:

signal_fields (SignalFields)
