NAME

6       HPXcvt - Reorganise HEALPix data into a 2-D FITS image
7

SYNOPSIS

9       HPXcvt [-C<col>] [-c<sys>] [-n|-r] [-q<quad>] [-x<n|s>]
10

DESCRIPTION

12              [<infile> [<outfile>]]
13
14       HPXcvt  reorganises HEALPix data into a 2-D FITS image with HPX coordi‐
15       nate system.  The input data may be stored in a FITS file as a  primary
16       image  or image extension, or as a binary table extension.  Both NESTED
17       and RING pixel indices are supported.  The input and output  files  may
18       be  omitted  or  specified  as "-" to indicate stdin and stdout respec‐
19       tively.

OPTIONS

22       -C<col>
23              Binary table column number from which to read  data,  default  1
24              (n.b. WMAP exclusion masks are in column 2).
25
26       -c<sys>
27              Specify the coordinate system to be used to label the output map
28              if the COORDSYS keyword is absent from the  input  FITS  header.
29              Recognised  values  are g (galactic), e (ecliptic) or q (equato‐
30              rial).
31
32       -n|-r  Assume n(ested) or r(ing) organization if the  ORDERING  keyword
33              is absent from the input FITS header.
34
35       -q<quad>
36              Recentre longitude at quad(mod 4) x 90 degrees, where quad(rant)
37              is an integer.
38
39       -x<n|s>
40              Use a north-polar or south-polar layout (XPH).
