name & dimensionality | kind | in/out | description |
---|---|---|---|
nsmax | I4B | IN | the Nside value of the map to analyse. |
nlmax | I4B | IN | the maximum l value for the analysis. |
nmmax | I4B | IN | the maximum m value for the analysis. |
spin | I4B | IN | the spin s of the maps to be analysed (only its absolute value is relevant). |
map(0:12*nsmax**2-1, 1:2) | SP/ DP | IN | |s|S+ and |s|S- input maps |
alm(1:2, 0:nlmax, 0:nmmax) | SPC/ DPC | OUT | The |s|a+lm and |s|a-lm output values. |
zbounds(1:2), OPTIONAL | DP | IN | section of the map on which to perform the alm
analysis, expressed in terms of
![]() |
w8ring(1:2*nsmax,1:2), OPTIONAL | DP | IN | ring weights for quadrature corrections. If ring weights are not used, this array should be 1 everywhere. |
Analyses spin 5 and -5 maps. The maps have an Nside of 256, and the analysis is performed up to 512 in l and m. The resulting alm coefficients for are returned in alm.
