ialteralm
ialteralm is an interface to 'alteralm' F90 facility. It requires some disk space on which to write the parameter file and the other temporary files. Most data can be provided/generated as an external FITS file, or as a memory array.

This example script reads the test (polarised)located in $HEALPIX/test/alm.fits and rotates them from Galactic to Equatorial coordinates, it then synthetizes a map out of those, and finally plots its I and Q Stokes components (in Equatorial coordinates)
