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) .. _WFPDB: http://www.skyarchive.org/1995LNP...454..412Thttps://dc.g-vo.org/wfpdb/q/cone/infoIsServedByGAVO Data Center TAP servicehttp://dc.g-vo.org/wfpdb/q/cone/scs.xml?https://dc.g-vo.org/wfpdb/q/cone/scs.xml?GETapplication/x-votable+xmlRARight Ascension (ICRS decimal)degpos.eq.rarealDECDeclination (ICRS decimal)degpos.eq.decrealSRSearch radiusdegrealwfpdbidWFPDB identifier of the plate, consisting of an observatory identifier, the instrument aperture, an instrument suffix, a plate number, and a suffix to it.meta.id;meta.maincharepochEpoch of observation start (UT)yrtime.epochrealobjectObject or field name as given by observermeta.id;srccharobject_typeType of the target objectsrc.classcharwavebandSpectral Bandinstr.bandpasscharresponseformatFile format requested for output.meta.code.mimecharmaxrecMaximum number of records returned.
