Get the bandpass mismatch field of the detector The formalism is based on the paper by Duc Thuong Hoang et al., 2017, JCAP, DOI: 10.1088/1475-7516/2017/12/015, Sec. 3.2

Parameters:

  • scan_field (ScanFields) – scan field instance

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

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

  • gamma_T_list (List[float]) – list of coefficient of the sky signal which corresponds to the bandpass mismatch of the Bottom detector

  • gamma_B_list (List[float]) – list of coefficient of the sky signal which corresponds to the bandpass mismatch of the Top detector

  • components (List[np.ndarray]) – list of the components (e.g. synchrotron and dust) of the temperature sky map
