A routine for converting GALPROP-generated HealPix skymaps to a compatible format which can be plotted by Aladin (v7), available from CDS at http://aladin.u-strasbg.fr. This allows free rotation of the sphere, avoiding the distortions of Aitoff and other projections often used. It is a very practical way to view and prepare skymap plots of GALPROP output.
GALPROP outputs a spectrum per HealPix pixel, while Aladin requires each energy to be stored as a column. A conversion is required to...
