name & dimensionality | kind | in/out | description |
---|---|---|---|
nlmax | I4B | IN | the maximum l value used for the alm. |
nmmax | I4B | IN | the maximum m value used for the alm. |
alm1(1:p, 0:nlmax, 0:nmmax) | SPC/ DPC | IN | First set of alm values. p is 3 or 1 depending on wether polarisation is included or not. In the former case, the first index runs from 1 to 3 corresponding to (T,E,B). |
alm2(1:p, 0:nlmax, 0:nmmax) | SPC/ DPC | IN | Second set of alm values. |
cl(0:nlmax,1:d) | SP/ DP | OUT | resulting auto or cross power spectra.
If both alm1 and alm2 are present, cl will be their cross power spectrum.
If only alm1 is present,cl will be its power spectrum.
If d=1, only the temperature spectrum ClTT will be output.
If d=4 and p=3, the output will be ClTT, ClEE, ClBB
and ClTE.

cl_auto will contain the (auto) power spectrum of the alm coefficients alm1 up to l= 128, cl_cross will be the cross power spectra of the two sets of alm coefficients alm1 and alm2, while cl_sym will be a symmetrized version of cl_cross.
