Report on the lunar ranging at McDonald Observatory for the period October 16, 1974 to February 11, 1975

Abstract

The four lunations between 16 October, 1974 and 11 February, 1975 were active in our continuing program to upgrade the capabilities of the McDonald Lunar Laser Ranging Station. Numerous changes were installed during this period designed to increase the overall reliability and performance of the laser equipment. The ranging operations proceeded routinely but at a somewhat slower acquisition rate due to relatively poor weather and the intermingled R&D efforts.
