sbm.SignalFields.elliptical_beam_field#

static SignalFields.elliptical_beam_field(scan_field, mdim: int, alm: ndarray, blm: ndarray, use_hwp=False)[source]#

Get the elliptical beam convolved field

Parameters:

  • scan_field (ScanFields) – scan field instance

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

  • alm (np.ndarray) – spherical harmonic expansion coefficients of sky

  • blm (np.ndarray) – spherical harmonic expansion coefficients of beam

  • use_hwp (bool) – whether the observation uses HWP or not

Returns:

elliptical beam convolution field of the detector

Return type:

signal_fields (SignalFields)
