Impersonal Techniques of Transit Circle Observations. “The Carlsberg Automatic Meridian Circle”
Published online by Cambridge University Press: 04 August 2017
Abstract
The conventionel reversible meridian circle of Copenhagen University, has over the last years been fully automated, and equipped with a new photoelectrical transit micrometer and a revised photoelectric circle recording system. Setting, observation and data recording is completely controlled by two minicomputers, therefore the presence of an observer is needed only for emergency situations, and for the reduction procedure. The telescope has been succesfully tested over a two year period in Brorfelde, resulting in two published catalogues with mean errors similar to those previously obtained with the photographic micrometer. The magnitudes were also measured and the limiting magnitude in Brorfelde was mv = 12.
In the autumn of 1983 the telescope was moved to the Canarian island La Palma, where it is currently being installed.
