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/wfpdb.archives A table of plate archives included in the WFPDB or scheduled for inclusion, as well as the properties of the instruments used to take the data.509instr_idWFPDB-internal instrument designationmeta.id;instrcharnullablearchive_idWFPDB-internal archive designation, consisting of the instrument id, the archive code, and the site code.meta.id;meta.maincharindexedprimarywfpdb_statusInclusion status of plates from this archive: * - at disposal in SSADC, not yet converted in computer-readable form, ** - in preparation in SSADC, converted in computer readable form, *** - included in the WFPDB and available on-line.meta.codecharnullableinstr_nameOriginal name of the instrument as used by the relevant observatorymeta.id;instrcharnullablearchive_locationLocation of the plate archivemeta.id;instr.obstycharnullablearch_partCode for a sub-archive when an instrument's archive is split across several sitesintinst_nameName of the hosting institutioncharnullablesite_codeCode for the instrument site when the instrument was operated from several locations.meta.idcharsite_nameObservatory sitemeta.id;instr.obstycharnullablecountryCountry the observatory is located in.meta.id;pos.earthcharnullablempc_numberMinor Planet Center observatory codemeta.id;instr.obstyintnullabletime_zoneTime difference to Greenwichhtime;arith.difffloatnullablelongGeographical longitude of the observatory.degpos.earth.lonfloatnullablelatGeographical latitude of the observatory.degpos.earth.latfloatnullablealtitudeAltitude of the observatory.mpos.earth.altitudefloatnullablen_tubesNumber of telescope tubes.meta.number;instr.telcharnullableapertureClear aperture of the telescope.mphys.size;instr.telfloatnullablediameterDiameter of the primary mirror or the objective lensmfloatnullablefocal_lengthFocal length of the telescopeminstr.tel.focalLengthfloatnullableplate_scalePlate scalearcsec/mmfloatnullableinst_typeInstrument type: Ast-astrograph, Cam-camera, FEC-fish eye camera, Men-meniscus, RCr-Ritchey-Chretien, Rfl-reflector, Rfr- refractor, Sch-Schmidtcharnullableang_sizeMaximum angular size of the field of view.degphys.angsize;instr.fovfloatnullableop_beginYear telescope operations started.yrtime.epochfloatnullableop_endYear telescope operations ended.yrtime.epochfloatnullabledet_typeDetector used: blank--plate, F--film, X--film and platemeta.code;instrcharnullablen_directNumber of direct plates in the archive.meta.number;obsintnullablen_prismNumber of prism plates in the archive.meta.number;obsintnullablecontactName of the contact person.charnullable
