HPXcvt1
Reorganise healpix data into a 2-d fits image
Usage
HPXcvt [-C<col>]
[-c<sys>]
[{-n | -r}]
[-q<quad>]
[{-x<n | s>}]
Overview
-
[<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).
