Abstract

As a part of the establishment of a unified longitude system for the European Triangulation Network the difference in longitude between the reference points Merate and Milano was measured with a Danjon Astrolabe. This paper describes the results of a one-step adjustment of these observations including additional parameters for effects like personal equations and catalogue errors.
