write_bintab*
This routine creates a binary FITS-file from a HEALPix map. The routine can save a temperature map or both temperature and polarisation maps (T,Q,U) to the file.
Location in HEALPix directory tree:
src/f90/mod/fitstools.f90
FORMAT call write_bintab*(
map, npix, nmap, header, nlheader, filename [, extno]
)
Arguments appearing in italic are

EXAMPLE:
call write_bintab (map,12*32**2,3,header,120,'map.fits')
Makes a binary FITS-file called `map.fits' from the HEALPix maps (T,Q,U) in the array map(0:12*32**2-1,1:3). The number of pixels 12*32**2 corresponds to the number of pixels in a Nside=32 HEALPix map. The header for the FITS-file is given in the string array header and the number of lines in the header is 120.
