cds-question@unistra.frinfrared-sourcesoccultationLunar occultations (LO) provide a unique combination of high angular resolution and sensitivity at near-infrared wavelengths. At the ESO Very Large Telescope, it is possible to achieve about 1 milliarcsecond (mas) resolution and detect sources as faint as K~12mag. We have taken advantage of a passage of the Moon over two crowded and reddened regions in the direction of the inner part of the Galactic bulge to obtain a high number of occultation light curves over two half nights. Our goal was to detect and characterize new binary systems, and to investigate highly extincted and relatively unknown infrared sources in search of circumstellar shells and similar peculiarities. Our target list included a significant number of very late-type stars, but the majority of the sources was without spectral classification.2011A&A...532A.101Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/532/A101CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/123 : Lunar Occultations of IRAS Point Sources: 1986-1990I/142 : Lunar Occultations of IRAS Point Sources: 1991-2000VI/132 : Lunar Occultation Archive (Herald+ 2010)J/A+AS/80/215 : Lunar occultations of weak radio sources (Akujor+, 1989)J/A+AS/110/107 : Lunar occultations (Meyer+ 1995)J/AJ/112/2786 : 1985-1995 lunar occultations at TIRGO (Richichi+ 1996)J/A+A/522/A65 : Lunar occultations at the ESO VLT (Richichi+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/532/A101https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/532/A101http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/532/A101https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/532/A101https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/532/A101http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/532/A101GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/532/A101/table2 (List of the recorded occultation events)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/532/A101/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/532/A101/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/532/A101/table2?GETtext/xml+votable180.050000true270.3657083-25.636750.0055555555555555566/28877 28879 28882 28888 28951 28956-289578.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/532/A101?format=asciiInfrareddefaultJ/A+A/532/A101/table2List of the recorded occultation eventsrecnoRecord number assigned by the VizieR team.
