VizieR Online Data Catalog: 1996-2009 optical photometric monitoring for 3C 66A (Fan+, 2018)
Abstract
The present photometric observations were done with the 1.56 m telescope at ShAO from 1996 December 11 to 2009 December 28. The observations during the period of 1996 December-2002 August were obtained using a liquid nitrogen-cooled CCD camera (1024x1024 pixels, 1 pixel=0.019 mm), while those during the period of 2002-2009 August were obtained using a new liquid nitrogen-cooled CCD camera (2048x2048 pixels, SITe CCD chip). The filters, the seeing, and the data processing soft packages were described in our previous work by Tao et al. (2004PASP..116..634T). For the observations of 3C 66A, we used integration times of 120 s typically for I and R, and 240 s for V depending on sky conditions and the brightness of the target.
