Build your own photospheres

Using the hips2fits service, you can easily generate your own photospheres from your favorite HiPS datasets.
You will have to use this template:
http://alasky.u-strasbg.fr/hips-image-services/hips2fits?
    hips=<HiPS-ID>&
    width=<width>&
    height=<height>&
    ra=<image-center-RA>&
    dec=<image-center-declination>&
    coordsys=<icrs|galactic>&
    fov=360&
    projection=CAR&
    format=jpg

The following conditions must be met:

  • projection must be CAR
  • fov must be equal to 360
  • height must be half of the width
  • format must be set to jpg
  • hips value must match the identifier of one of the existing HiPS (see this page giving the up-to-date list of available HiPS)
