cartview reads in a HEALPix sky map in FITS format and generates a cartesian projection of it, that can be visualized on the screen or exported in a GIF, JPEG, PNG, PDF or Postscript file. cartview allows the selection of the coordinate system, map size, color table, color bar inclusion, linear, log, hybrid or histogram equalised color scaling, maximum and minimum range for the plot, plot-title etc. It also allows the representation of the polarization field.

makes a cartesian cylindrical projection of map (see Figure 1a on page ) after an arbitrary rotation, with a graticule grid (with a 45o step in longitude and 30o in latitude) and an arbitrary triangular outline
