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 (XPH).
