Parameters read by smoothing_cxx: fwhm_arcmin (double): FWHM (in arcmin) of the Gaussian beam used for smoothing. If the value is negative, the smoothing of a Gaussian beam with an FWHM of -fwhm_arcmin will be _removed_ from the input map. nlmax (integer): maximum order of l infile (string): input file containing the Healpix map outfile (string, default=""): output file for the smoothed Healpix map polarisation (bool): if false, only an intensity map is smoothed if true, an IQU map is smoothed weighted (bool, default=false): if true, weighted quadrature is used if (weighted) healpix_data (string): directory containing the Healpix data files endif iter_order (integer, default=0) number of iterations for the analysis (0: standard analysis) double_precision (bool, default=false): if false, a_lm are read/written in single precision, otherwise in double precision.
