A method for applying seasonal corrections to star-coordinate adjustments
Abstract
A modification for the chain adjustment of the coordinates of stars is proposed. It enables a correction for instrumental and refraction errors, if they are linear night trends. The method is tested for group as well as for non-group observations. The advantages of the method are shown using Pulkovo time service observations.
