Abstract

Results from Lunar Laser Ranging data analysis are presented: (a) the values and statistics of UT1 determined by three stations are given; (b) the lunar tidal accelerationnis found to be −24.9 ± 1.0 arc sec/century2; (c) the tidal-effect coefficientk/Cfor UT1 is shown to be in strong agreement with the theoretical value; and (d) corrections to the IAU values of precession and nutation are estimated.
