+Parameters read by syn_alm_cxx:
+
+nlmax (integer):
+  maximum order of l
+
+nmmax (integer):
+  maximum order of m (must not be larger than nlmax, default=nlmax)
+
+infile (string):
+  input file containing the CMB power spectrum
+
+outfile (string):
+  output file name for the calculated a_lm
+
+rand_seed (integer):
+  random-number seed
+
+fwhm_arcmin (real):
+  FWHM (in arcmin) of a Gaussian beam, which is used to smooth the
+  resulting sky a_lm (default=0)
+
+polarisation (bool):
+  if false, only the intensity a_lm are generated,
