Table Description:
This table is available for ADQL queries and through the TAP endpoint.
Resource Description:
The Wide-Field Plate Database (WFPDB) contains the descriptive information for the astronomical wide-field (>1°) photographic observations stored in numerous archives all over the world. The total number of these observations, obtained since the end of the 19th century with more then 200 instruments (telescopes) is about 2 550 000 from 509 archives.
The WFPDB is continually being updated, providing currently access to the information for about 640 000 plates from 117 plate archives (30% of the estimated total number of wide-field plates)
