cds-question@unistra.frquasarsgravitational-lensingapparent-magnitudeSpatially resolved CCD photometry of the Q2237+0305 gravitationally lensed quasar in V, R and I spectral bands from observations with the Maidanak 1.5-m telescope made in 1995-2000 is presented. For each of the four quasar components, - A, B, C and D, - stellar magnitudes for 78 dates in R filter, and for 17 dates in V and I and shown in Tables 4-6. The color indices V-R and V-I for 17 dates during 1995-2000 are also presented (Table 7), which permitted to analyse a behavior of colors of the lensed quasar images in microlensing, and to discover a significant correlation between the color changes and magnitude changes in the sense, that the components tend to become bluer as their brightness increases.2004A&A...420..447Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/420/447CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/412/707 : Absorption-line systems in QSO - CoALS (Ryabinkov+, 2003)J/ApJS/77/203 : QSO absorption systems (Junkkarinen+ 1991)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/420/447https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/420/447http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/420/447https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/420/447https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/420/447http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/420/447GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/420/447/table4Photometry of Q2237+0305A,B,C,D in the R band from observations in 1995-1999.CCDCCD camerameta.id;instrcharrecnoRecord number assigned by the VizieR team.
