Determination of Nutation Based on Observations with the Pulkovo Polar Tube
Since 1953 regular observations have been carried out with the Polar photographic tube at Pulkovo [1, 2, 3]. A detailed description of the observational procedure, the data reduction technique, and error sources were given by Potter .
