call alm2map_spin*( nsmax, nlmax, nmmax, spin, alm, map )
name & dimensionality | kind | in/out | description |
---|---|---|---|
nsmax | I4B | IN | the Nside value of the map to synthesize. |
nlmax | I4B | IN | the maximum l value used for the alm. |
nmmax | I4B | IN | the maximum m value used for the alm. |
spin | I4B | IN | spin s of the maps to be generated (only its absolute value is relevant). |
alm(1:2, 0:nlmax, 0:nmmax) | SPC/ DPC | IN | The |s|a+lm and |s|a-lm values to make the map from. |
map(0:12*nsmax**2-1, 1:2) | SP/ DP | OUT | |s|S+ and |s|S- output maps |
Make spin-4 maps from the alm passed in alm. The maps have Nside of 256, and are constructed from alm values up to 512 in l and m.
