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.
