This page describes the contents of the PanSTARRS-1 system metadata database tables.  These tables include information on the flag values, filters, surveys, and other similar metadata. The information is not specific to individual objects but is useful in interpreting values from the object data tables. These descriptions are extracted from the PSPS Schema Browser interface created by the University of Hawaii.
