Pan-STARRS is a system for wide-field astronomical imaging developed and operated by the Institute for Astronomy at the University of Hawaii. Pan-STARRS1 (PS1) is the first part of Pan-STARRS to be completed and is the basis for Data Release 1 (DR1). The PS1 survey used a 1.8 meter telescope and its 1.4 Gigapixel camera (GPC1; see PS1 GPC1 camera) to image the sky in five broadband filters (g, r, i, z, y). The PS1 Science Consortium funded the operation of the Pan-STARRS1 telescope, situated at Haleakala Observatories near the summit of Haleakala in Hawaii, for the purposes of astronomical research. The PS1 consortium is made up of astronomers and engineers from 14 institutions from six countries.\n\nThe Pan-STARRS Data Release 1 Object Catalog "Best" filtered exists in the MAST holdings and is thus available through a cone search. The filtered data is a ~2billion row subset based on an object having more than 2 detections.\nAll available catalogs are listed at http://archive.stsci.edu/vo/mast_services.html.
