THE SLOPE OF ΔM LIGHT CURVE DEPENDING UPON THE ITS LOCATION IN CCD FRAME

BV observations for V523 Cas were performed with 1.8m telescope and 2K CCD camera at Bohyunsan Optical Astronomy Observatory, Korea, on October 27, 1999. ∆m light curves for 11 comparison objects were made. It was found that their light curve slopes are different each other. Factor analysis for item...

Summary:BV observations for V523 Cas were performed with 1.8m telescope and 2K CCD camera at Bohyunsan Optical Astronomy Observatory, Korea, on October 27, 1999. ∆m light curves for 11 comparison objects were made. It was found that their light curve slopes are different each other. Factor analysis for items of slope, (b-v), magnitude, X pixel, and Y pixel results that there is strong correlation between the slope and the location (X,Y). It might be due to problems of CCD cooling system.
