cds-question@unistra.frinfrared-sourcesmultiple-starsLunar occultations (LO) are a very efficient and powerful technique that achieves the best combination of high angular resolution and sensitivity possible today at near-infrared wavelengths. Given that the events are fixed in time, that the sources are occulted randomly, and that the telescope use is minimal, the technique is very well suited for service mode observations. We have established a program of routine LO observations at the VLT observatory, especially designed to take advantage of short breaks available in-between other programs. We have used the ISAAC instrument in burst mode, capable of producing continuous read-outs at millisecond rates on a suitable subwindow. Given the random nature of the source selection, our aim has been primarily the investigation of a large number of stellar sources at the highest angular resolution in order to detect new binaries. Serendipitous results such as resolved sources and detection of circumstellar components were also anticipated.2010A&A...522A..65Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/522/A65CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVI/132 : Lunar Occultation Archive (Herald+ 2010)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/112/2786 : 1985-1995 lunar occultations at TIRGO (Richichi+ 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/522/A65https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/522/A65http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/522/A65https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/522/A65https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/522/A65http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/522/A65GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/522/A65/table1 (List of the recorded occultation events)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/522/A65/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/522/A65/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/522/A65/table1?GETtext/xml+votable180.050000true137.569517.656250.0055555555555555566/4371 4480 4512 4715 4801 27441 27443 27538 27544 27546 28789 28791 28948 28960-28961 29187 29190 29193 29195 29198 29217 42977 44326 44329 44331-44332 44418 44615 44624 44626 48062-48063 48090-48091 48100-48102 48112-48113 48700 48754-48755 48758 48772 487798.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/522/A65?format=asciiInfrareddefaultJ/A+A/522/A65/table1List of the recorded occultation eventsrecnoRecord number assigned by the VizieR team.
