  2. Use any of the filters Target Constrains, Timestamps... to discriminate your search.
  3. Preview results and select files to download individually or in bulk.

Example searches

  • By Principal Investigator: see all of the papers produced by a P.I. .
  • By coordinates: use RA/Dec (sexagesimal or decimal) and set a search radius, cone search is also available.
  • By time: restrict to an observing night or campaign window.
