cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryWe present the results of CCD BVI Johnson-Cousins photometry down to V~19mag in the regions of the unstudied stellar groups Pismis 23 and BH 222, both projected close to the direction towards the Galactic centre. We measured V magnitude and B-V and V-I colours for a total of 928 stars in fields of about 4'x4'.2002A&A...388..179Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/388/179CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/107/39 : IC 2714 UBV photometry (Claria+ 1994)J/ApJS/116/263 : VI photometry of open clusters (Piatti+ 1998)J/A+AS/127/423 : VI photometry of Westerlund 1 and 2 (Piatti+ 1998)J/A+AS/128/131 : UBV photometry of NGC 2323 (Claria+ 1998)J/A+A/360/529 : BVI photometry of 4 young open clusters (Piatti+, 2000)J/A+A/370/931 : BVI photometry of 4 open clusters (Piatti+, 2001)J/A+A/375/30 : Radial velocities in open clusters (Mermilliod+, 2001)J/A+A/379/453 : BVI photometry of 5 open cluster candidates (Piatti+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/388/179https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/388/179http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/388/179https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/388/179https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/388/179http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/388/179GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/388/179/table2 (Magnitudes and colours of stars in the field of Pismis 23)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/388/179/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/388/179/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/388/179/table2?GETtext/xml+votable180.050000true246.0402397-48.91872580.005555555555555556Cone search capability for table J/A+A/388/179/table3 (Magnitudes and colours of stars in the field of BH 222)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/388/179/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/388/179/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/388/179/table3?GETtext/xml+votable180.050000true259.72998917-38.2970.0055555555555555566/42216 42438https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/388/179?format=asciiOpticalInfrareddefaultJ/A+A/388/179/table2Magnitudes and colours of stars in the field of Pismis 23recnoRecord number assigned by the VizieR team.
