f2map

Description

f2map performs conversion of a GLESP map either to HEALPix format or to equidistant grid FITS format. In conversion to HEALPix, f2map performs repixelization using spline interpolation algorithm (default) or direct mapping.

The repixelization to HEALPix format can be performed with a reduced resolution.

Examples

• f2map map.glesp.fits -o map.healpix.fits
  converts the GLESP map ' map.glesp.fits' to HEALPix format and outputs to file ' map.healpix.fits'.

• f2map map.glesp -rp -o map.healpix -n 2
  converts the GLESP map ' map.glesp' to HEALPix format via direct mapping and outputs to file ' map.healpix'. The resolution is decreased by a factor of 2.

• f2map map.glesp -bf -o map.feqdis
  converts the GLESP map ' map.glesp' to equidistant grid FITS format and outputs to file ' map.feqdis'.
