        Parameters
        ----------
        band : int
            The module nominal frequency, in GHz.
        scene : QubicScene, optional
            The discretized observed scene (the sky).
        block : tuple of slices, optional
            Partition of the samplings.
        absolute : boolean, optional
            If true, the scene pixel values include the CMB background and 
            the fluctuations in units of Kelvin, otherwise it only represent 
            the fluctuations, in microKelvin.
        kind : 'I', 'QU' or 'IQU', optional
            The sky kind: 'I' for intensity-only, 'QU' for Q and U maps,
            and 'IQU' for intensity plus QU maps.
        nside : int, optional
            The Healpix scene's nside.
        instrument : QubicInstrument, optional
            The QubicInstrument instance.
        calibration : QubicCalibration, optional
            The calibration tree.
        detector_fknee : array-like, optional
            The detector 1/f knee frequency in Hertz.
        detector_fslope : array-like, optional
            The detector 1/f slope index.
        detector_ncorr : int, optional
            The detector 1/f correlation length.
        detector_nep : array-like, optional
            The detector NEP [W/sqrt(Hz)].
        detector_ngrids : 1 or 2, optional
            Number of detector grids.
        detector_tau : array-like, optional
            The detector time constants in seconds.
        filter_relative_bandwidth : float, optional
            The filter relative bandwidth delta_nu/nu.
        polarizer : boolean, optional
            If true, the polarizer grid is present in the optics setup.
        primary_beam : function f(theta [rad], phi [rad]), optional
            The primary beam transmission function.
        secondary_beam : function f(theta [rad], phi [rad]), optional
            The secondary beam transmission function.
        synthbeam_dtype : dtype, optional
            The data type for the synthetic beams (default: float32).
            It is the dtype used to store the values of the pointing matrix.
        synthbeam_fraction: float, optional
            The fraction of significant peaks retained for the computation
            of the synthetic beam.
        max_nbytes : int or None, optional
            Maximum number of bytes to be allocated for the acquisition's
            operator.
        nprocs_instrument : int, optional
            For a given sampling slice, number of procs dedicated to
            the instrument.
        nprocs_sampling : int, optional
            For a given detector slice, number of procs dedicated to
            the sampling.
        comm : mpi4py.MPI.Comm, optional
            The acquisition's MPI communicator. Note that it is transformed
            into a 2d cartesian communicator before being stored as the 
            'comm' attribute. The following relationship must hold:
                comm.size = nprocs_instrument * nprocs_sampling
