Description
The table contains data on photographic plates of the Einsteinturm as physical objects. For the release, we enhanced the table with observation data pertaining to the plate, since there is a 1:1 relation; one plate corresponds to an observation with a short exposure time. See also the scan table. Unique Identifier plate_id
