change_polcconv
This routine will change the sign of the U Stokes parameters (and related quantities, such as the TU and QU cross-correlations) and update the 'POLCCONV' FITS keyword where applicable. The recognised format are:
- standard Healpix full sky polarised format
- cut sky Healpix polarised format
- WMAP 2nd year polarised format
change_polcconv, 'map_cosmo.fits','map_iau.fits',/c2i |
Modify the file 'map_cosmo.fits', which was using the 'COSMO' convention for polarisation coordinate convention into 'map_iau.fits' which uses the 'IAU' convention
