Digitized photographic plates (applause_dr1.plate)

Description

The table contains data on photographic plates or films as physical objects. An entry in this table does not guarantee that a scan of the plate is available. It lists all photographic plates and films, which were digitzed and ingested into the APPLAUSE archive. See also the scan table. Unique Identifier plate_id
