sbm.sim_bandpass_mismatch

sbm.sim_bandpass_mismatch(config: Configlation, syst: Systematics, mbsparams: MbsParameters, detector_list: list | None = None, base_path: str | None = None)

Simulate the bandpass mismatch systematics.

Parameters:

• config (Configlation) – The configuration class

• syst (Systematics) – The systematics class

• mbsparams (lbs.MbsParameters) – The parameters for the litebird_sim

• detector_list (list of lbs.DetectorInfo) – List of DetectorInfo for each detector considered, generated with lbs.DetectorInfo. In each DetectorInfo, the band_weights are the bandpass for that detector. These bandpasses are used to compute the foreground input maps. If None, the foreground maps are computed at the central freq of the channel.

• base_path (str) – The base path for the HDF5 files containing the cross-link maps

Returns:

The observed map after the map-making

returned_input_map (np.ndarray): The input map for the simulation

Return type:

observed_map (np.ndarray)
