NAME

       HPXcvt - Reorganise HEALPix data into a 2-D FITS image

SYNOPSIS

       HPXcvt [-C<col>] [-c<sys>] [-n|-r] [-q<quad>] [-x<n|s>]

DESCRIPTION

              [<infile> [<outfile>]]

       HPXcvt  reorganises HEALPix data into a 2-D FITS image with HPX coordinate system.  The input data may be
       stored in a FITS file as a primary image or image extension, or as a binary table extension.  Both NESTED
       and RING pixel indices are supported.  The input and output files may be omitted or specified as  "-"  to
       indicate stdin and stdout respectively.

OPTIONS

       -C<col>
              Binary  table  column  number from which to read data, default 1 (n.b. WMAP exclusion masks are in
              column 2).

       -c<sys>
              Specify the coordinate system to be used to label the output map if the COORDSYS keyword is absent
              from the input FITS header.  Recognised values are g (galactic), e (ecliptic) or q (equatorial).

       -n|-r  Assume n(ested) or r(ing) organization if the ORDERING keyword  is  absent  from  the  input  FITS
              header.

       -q<quad>
              Recentre longitude at quad(mod 4) x 90 degrees, where quad(rant) is an integer.

       -x<n|s>
              Use a north-polar or south-polar layout.
