Description
Summary:The algorithm of the “mean weighted” comparison star for the photometry using CCD-cameras, has been described. The expressions for self-consistent determination of the weights and scatter of the comparison stars and the “mean weighted” star have been presented. This algorithm of using the “artificial” star instead of one control star allows to improve accuracy of the comparison star determination by dozens of percent or sometimes by few times. The computer program “Multi-Column View” (MCV) has been described, which allows to visualize, delete or interpolate the data before applying the algorithm of the “mean weighted” comparison star.
