This page describes the contents of the PanSTARRS-1 database object and detection tables that contain data from some bad skycells. These tables are identical in structure to the main tables (e.g, ObjectThinBadSkycells has the same columns as ObjectThin). They include information on sources that are identified as bad in both the PS1 DR1 and DR2 data release releases because there was a problem with alignment of some images near the north equatorial pole that led to poor photometry and astrometry. We have marked the photometric measurements as bad for these objects in the main database tables, but the original information is available in these bad skycell tables.
Note that these values are considered of very poor quality, so they should be used with great caution.
The starting point for the PS1 data archive is at Pan-STARRS1 data archive home page.
