First Results From the New Micrometer on the Carlsberg Automatic Meridian Circle
Published online by Cambridge University Press: 19 July 2016
Abstract
A new micrometer has been in operation on the Carlsberg Automatic Meridian Circle since May 1988. The zenith mean error for one observation has improved from O.″19 to 0.″14 and the limiting magnitude from 13m.2 to 14m.8. The first meridian observations of Pluto and observations of nine extragalactic objects are briefly discussed.
