cds-question@unistra.frradio-sourcesWe present the results of a 3.3yr project to monitor the flux density of Sagittarius A* at 2.0, 1.3, and 0.7cm with the Very Large Array. Between 2000.5 and 2003.0, 119 epochs of data were taken with a mean separation between epochs of 8 days. After 2003.0, observations were made roughly once per month for a total of nine additional epochs. Details of the data calibration process are discussed, including corrections for opacity and elevation effects, as well as changes in the flux density scales between epochs. The fully calibrated light curves for Sgr A* at all three wavelengths are presented.2004AJ....127.3399Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/127/3399CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/127/3399https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/127/3399http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/127/3399https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/127/3399https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/127/3399http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/127/3399GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefaultJ/AJ/127/3399/table2Calibrated Flux Density of Sgr A* (with corrected values from erratum published in 2005, AJ, 129, 2511)recnoRecord number assigned by the VizieR team.
