generate_beam
call generate_beam( fwhm_arcmin, lmax, beam [, beam_file] )
name & dimensionality | kind | in/out | description |
---|---|---|---|
fwhm_arcmin | DP | IN | fwhm size of the gaussian beam in arcminutes. |
lmax | I4B | IN | maximum l value of the window function. |
beam(0:lmax,1:p) | DP | OUT | beam window function generated. The second index runs form 1:1 for temperature only, and 1:3 for polarisation. In the latter case, 1=T, 2=E, 3=B. |
beam_file(LEN=filenamelen) (OPTIONAL) | CHR | IN | name of the file containing the (non necessarily gaussian) window function Bl of a circular beam. If present, it will override the argument fwhm_arcmin. |
Generates the window function of a gaussian beam of FWHM = 5 arcmin, for.
