VRI photometry of lensed quasar QSO B2237+0305

DOI

Spatially 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.
