Currently the primary access to the PanSTARRS catalog is through database queries using the MAST CasJobs interface, and the primary access to the PS1 images is through the PS1 Image Cutout Service. There is also a simple web form to search the catalog for objects near a sky position and a VO-compatible cone search interface for simple positional searches. Both catalog and image interfaces can be used from scripts. In the future other methods will be added for retrieving PanSTARRS images and catalogs, including more options for the form interfaces and a sophisticated MAST Portal interface that has capabilities of browsing, filtering, plotting, etc.

The starting point for the PS1 data archive is at Pan-STARRS1 data archive home page.

Catalog Access Tools

The PanSTARRS catalog is a large database of the objects and measurements of their properties including astrometry, photometry, and morphology. It includes copious metatdata including links to the images that were used for the various object measurements. (Maybe include some stats on catalog/database size here.)

  • Search Forms: A simple web form searches the object catalog for objects near a search position.
    • http://archive.stsci.edu/panstarrs/search.php
    • The form includes a name resolver allowing positions to be specified using object names recognized by SIMBAD or NED.
    • The search results from this form can be returned in a variety of formats including HTML table, comma-separated values, etc. The columns returned can also be customized.
    • Currently the form has a single additional parameter to require the results to include only objects with more than one detection (the default is nDetections>1). This is useful to eliminate spurious objects from the catalog, which are usually detected at only a single epoch.
    • The form has an associated web service that can be used for programmatic (scripted) queries to the catalog.
  • VO Cone search: 
    • http://gsss.stsci.edu/webservices/vo/CatalogSearch.aspx?CAT=PS1V3OBJECTS&RA=<ra>&DEC=<dec-degrees>&SR=<radius-degrees>
    • A generic description of this multi-catalog service is available at http://gsss.stsci.edu/Software/WebServices.htm.

Image Access Tools

The PS1 images are available for the five PS1 filters for combined multi-epoch stacked images.

  • The PS1 Image Cutout Service provides color images, JPEG and FITS cutouts, an interactive image display, and full FITS image retrievals.
  • The image cutout service is programmatically accessible to allow downloading either cutouts or full images via a script.
