Gravitational lens Q2237+0305: reduction and analysis of the observational data. Koptelova E.A., Artamonov B.P., Shimanovskaya E.V., Bruevich V.V., Gusev A.S., Ezhkova O.V. <Astron. Zh. 84, 885 (2007)> =2007AZh....84..885K =2007ARep..51...797K
ADC_Keywords: Radio sources ; Photometry, VRI ; Photometry, CCD ; QSOs Abstract: The results of VRI photometry of the gravitationally lensed system Q2237+0305 carried out on the 1.5-m telescope of Maidanak observatory in 2004-2005 are presented. The distance between the components is of the order of 1".
