cds-question@unistra.froccultationLunar occultation timings from 1623 to the present time are brought together in a consistent format. The observations have been processed and reviewed to correct a range of data errors. Provisional reductions of the observations are provided. The reductions are based on the JPL-DE440 ephemerides, with limb corrections derived from satellite altimetry from the Lunar Orbiter Laser Altimeter of the Lunar Reconnaissance Orbiter. Almost all star positions are from Gaia EDR3, Hipparcos2, or UBAD.https://cdsarc.cds.unistra.fr/viz-bin/cat/VI/132CCatalogResearchIsServedByTAP VizieR generic servicerelated-tohttp://occultations.org.nz/index.htm/ : IOTA home page for Australasiahttp://www.iota-es.de/ : IOTA home page for Europehttp://astro-limovie.info/jclo/index.html : IOTA home page for Japanhttp://www.lunar-occultations.com/IOTA : IOTA home page for North Americahttps://pds-geosciences.wustl.edu/lro/lro-l-lola-3-rdr-v1/lrolol_1xxx/data/lola_gdr/cylindrical/img/ : The LRO-LOLA data used for limbhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VI/132Chttps://vizier.iucaa.in/viz-bin/VizieR-2?-source=VI/132Chttp://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VI/132Chttps://vizier.cds.unistra.fr/viz-bin/votable?-source=VI/132Chttps://vizier.iucaa.in/viz-bin/votable?-source=VI/132Chttp://vizieridia.saao.ac.za/viz-bin/votable?-source=VI/132CGETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultVI/132C/lunaroccLunar occultation archiveVDatum[ME] Vertical datum code (29)pos.earth.altitude;instr.obstycharrecnoRecord number assigned by the VizieR team.
