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 coordi-
nate 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 respec-
tively.
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 (equato-
rial).
-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 (XPH).
