The Results of the Photographic Positional Observations of Venus on the Wide-Field Astrograph of the Sternberg Astronomical Institute, Moscow State University, in 1969-1988

摘要

A new technique for the reduction of the observed position of Venus with a correction for the phase effect and photographic irradiation is briefly described. For the first time, a method for bringing the observed position of Venus into the system of standard exposure is proposed that considerably diminishes the random errors of a session and the whole line of observations. Original Venus observational material is presented together with accuracy estimations. The O-C difference yielded by the reduction procedure is plotted along both coordinate axes.
