cds-question@unistra.frvariable-starsinfrared-photometryWe report here the results of a 4-yr K-band (2.2mm) survey for large-amplitude variable stars in a 24x24arcmin^2^ area centred on the Galactic Centre. A total of 409 likely long-period variables (LPVs) were detected, for which positions, amplitudes, average magnitudes and periods were obtained whenever possible. The surface density of LPVs is more than ten times greater than in the Sgr I Baade window at l=-1.37{deg}, b=-2.63{deg}2001MNRAS.321...77Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/321/77CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/92/43 : Radio Obs. of OH/IR stars close to Gal.Center (Lindqvist+ 1992)J/A+AS/128/35 : New Sample of OH/IR stars (Sjouwerman+ 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/321/77https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/321/77http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/321/77https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/321/77https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/321/77http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/321/77GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/321/77/table2 (Large-amplitude variables found in the survey field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/321/77/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/321/77/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/321/77/table2?GETtext/xml+votable180.050000true266.450875-28.85697220.005555555555555556Cone search capability for table J/MNRAS/321/77/table1 (Survey field centres)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/321/77/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/321/77/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/321/77/table1?GETtext/xml+votable180.050000true266.422917-28.8480560.005555555555555556Cone search capability for table J/MNRAS/321/77/table4 (Objects found twice in the survey (because of overlapping fields))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/321/77/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/321/77/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/321/77/table4?GETtext/xml+votable180.050000true266.46782917-28.858930560.005555555555555556Cone search capability for table J/MNRAS/321/77/table5 (Result of searches for all known OH/IR stars in survey area and comparisons with previous work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/321/77/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/321/77/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/321/77/table5?GETtext/xml+votable180.050000true266.2135-29.1620.0055555555555555566/28827 28830https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/321/77?format=asciiInfrareddefaultJ/MNRAS/321/77/table2Large-amplitude variables found in the survey fieldrecnoRecord number assigned by the VizieR team.
