Gaia Archive Visualisation Service gallery

A range of resources for use in presentations of GDR1 data can be downloaded from the Gaia Archive Visualisation Service gallery ( ). They include:

  • Images showing integrated GDR1 source brightness and source density maps (all-sky and selected regions).
  • All-sky maps in Hierarchical Progressive Survey (HiPS) format for viewing with Aladin or other software supporting HiPS (the maps are based on a HEALPIX grid with NSIDE=8192).
  • FITS images of some regions. Contours or other overlays and manipulations for analysis or presentation purposes can be done with DS9, IRAF, Python and other software.
  • Large format images for dome projection. Large 16384x8192-pixel all-sky panoramas in a Cartesian plane projection, suitable for use in modern digital planetaria.
