wcs - World Coordinate Systems 
wcs [parameter=value] 
wcs
is the World Coordinate System. 
Polarization is an exceptional
case, since it’s enumerated (XX, YY, LL, etc.), but the community has assigned
integer values such that a usual NAXIS,CRPIX,CRVAL,CDELT,CTYPE can be used.
This is the AIPS/FITS convention.
