rotate_alm*
call rotate_alm*( lmax, alm_TGC, psi, theta, phi )
name & dimensionality | kind | in/out | description |
---|---|---|---|
nlmax | I4B | IN | maximum l value for the alm. |
alm_TGC(1:p,0:nlmax,0:nlmax) | SPC/ DPC | INOUT | complex alm values before and after rotation of the coordinate system. The first index here runs from 1:1 for temperature only, and 1:3 for polarisation. In the latter case, 1=T, 2=E, 3=B. |
psi | DP | IN | first rotation: angle ![]() ![]() ![]() ![]() |
theta | DP | IN | second rotation: angle ![]() |
phi | DP | IN | third rotation: angle ![]() |
Transforms scalar and tensor alm forto emulate a rotation of the underlying map by (
).
Rotate the alm from Ecliptic to Galactic coordinates.
