Consideration of the magnitude equation using exposures of different duration. II. Investigation of the magnitude equation for the astrograph (40/550) of the Main Astronomical Observatory of the Ukrainian Academy of Sciences.
Abstract
Investigation of the magnitude equation using the catalogue of reference stars has shown that photography with two exposures of different duration permitted to determine the effect of this error on the star position. Magnitude errors are +0arcsec.05 and -0arcsec.03 per stellar magnitude along the coordinates x and y, respectively.
