Abstract

In this paper, we consider a method for determining the coefficients of the transformation equations between different photometric systems based on the photometry of all field stars recorded during observations of the primary standards of one of the photometric systems. Using this method, the coefficients of color transformation equations between the photometric system of ASTRONIRCAM of the 2.5-m telescope KGO SAI MSU and the 2MASS all-sky survey catalog photometric system are obtained.
