cds-question@unistra.frsurveysvariable-starsinfrared-photometryThe Vista Variables in the Via Lactea (VVV) near-infrared (IR) variability survey explores some of the most complicated regions of the Milky Way bulge and disk in terms of high extinction and high crowding. We add a new wavelength dimension to the optical information available at the American Association of Variable Star Observers International Variable Star Index (VSX-AAVSO) catalogue to test the VVV survey near-IR photometry to better characterise these objects. We cross-match the VVV and the VSX-AAVSO catalogues along with Gaia Data Release 2 photometry and parallax. We present a catalogue that includes accurate individual coordinates, near-IR magnitudes (ZYJHKs), extinctions AKs, and distances based on Gaia parallaxes. We also show the near-IR CMDs and spatial distributions for the different VSX types of variable stars, including important distance indicators, such as RR Lyrae, Cepheids and Miras. By analysing the photometric flags in our catalogue, we found that around 20% of the stars with measured and verified variability are flagged as "non-stellar source", even when they are outside of the saturation and/or noise regimes. Additionally, we pair-matched our sample with the VIVA catalogue and found that more than half of our sources are missing from the VVV variability list, mostly due to low signal-to-noise observations or photometric problems with a small percentage due to failures in the selection process. Conclusions. Our results suggest that the current knowledge about variability in the Galaxy is biased to the nearby, low extincted stars. The present catalogue also provides the groundwork to characterise the results of future large variability surveys like the Vera C. Rubin Observatory's Legacy Survey of Space and Time in the heavily crowded and reddened regions of the Galactic plane, as wellas follow-up campaigns to characterise specific types of variables. The analysis of the miss-flagged stars can be used to improve the photometric classification of the VVV data allowing to expand the amount of data considered useful for science purposes. Besides, we provide an additional list of stars missed by the VIVA procedures for which the observations are actually good and they were missed due to some failure in the VIVA selection process.2021A&A...647A.169Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/647/A169CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)I/345 : Gaia DR2 (Gaia Collaboration, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/647/A169https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/647/A169http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/647/A169https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/647/A169https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/647/A169http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/647/A169GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/647/A169/catalog (Catalogue of known variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/647/A169/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/647/A169/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/647/A169/catalog?GETtext/xml+votable180.050000true270.56602667-42.353745560.0055555555555555563/448 450-451 4/1796 1798-1799 1810 2603 2610 2613 2638 2649 2652-2653 2655 5/7190-7191 7234-7235 7264 7266 7272 7301 7312-7313 7316-7317 7319 9473 9476-9477 10398-10399 10407 10417-10422 10424-10425 10438-10439 10444-10446 10449-10451 10456 10464 10538-10539 10541-10543 10550-10551 10556-10557 10583 10589-10591 10594-10595 10600 10617 10619 10624-10625 10628 10753-10756 10760 11946-11947 6/28752 28754-28755 28758-28759 28930 28954 28976 28978 29060-29062 29068 29096-29098 29184-29185 29188-29189 29200-29201 29203 29260-29261 29272-29273 29440 29442 29448 37889 37891 37897 37900-37901 37912 37952 41466-41467 41469-41471 41582-41583 41590-41591 41627 41639 41645-41647 41665-41667 41692-41694 41704-41706 41708 41712 41742-41743 41751 41788-41789 41793-41795 41828-41830 41832 41840-41841 41860-41861 41864 42150-42151 42162-42163 42187 42190-42191 42232-42234 42236-42237 42303 42325-42327 42331 42346-42347 42350-42351 42353 42355 42370-42371 42374-42375 42404-42406 42416-42417 42420-42421 42464-42465 42504-42506 42508 42516-42517 42560-42561 42836-42837 43009-43011 43028-43030 43032-43034 43044-43046 43048-43050 43136 47802-47803 47806-47807 478507.952274030004205e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/647/A169?format=asciiInfrareddefaultJ/A+A/647/A169/catalogCatalogue of known variablesNameVSX name (Name)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
