Parallax of the moon in terms of a world geodetic system
Abstract
The recent geodetic connection between Europe and South Africa along the 30th meridian east makes it possible to reinterpret the Greenwich and Cape observations of the lunar crater A made by Christie and Gill in the years 1905 to 1910. Crommelin's result for the correction of Hansen's value for mean parallax of the moon is expressed as a mean lunar distance in kilometers, which is compared with various results from dynamical theory, with O'Keefe and Anderson's determination from occultations, and with radar measure- ments. The Astrogeodetic World Datum serves as common reference system. As a by-product, the contra- dictions in the literature quoting Hansen's value for mean parallax are cleared up.
