This data set, received from the experimenter, contains analyzed data listed on 16-mm microfilm. The first 4 pages of each orbit printout contain selected program parameters. For each orbit printout, the following data are then listed in columns -- time in GMT, time in minutes (GMT), time in minutes since the reference epoch, time in minutes on the associated plot for that particular data point, and the Doppler residual (in Hz) calculated from a theoretical model containing (1) planetary perturbations, (2) earth rotation, (3) precise station locations, (4) tropospheric model, and (5) precise station transit times removed from the returned signal. Also listed are spacecraft altitude, spacecraft selenographic latitude and longitude, theoretical value of the Doppler shift calculated by the spline program used in the least squares, acceleration determined by analytic differentiation of the spline at the reference point, and a residual in Hz after the spline has fitted the Doppler residuals (good data show and rms residual of about .005 Hz or less). The data cover orbits 3, 4, 5, 7, 8, 10, 11, 13, and 14. Included on the microfilm is a copy of the article in 'Science' reporting these results, as well as a copy of the program used to analyze these data. Data from Apollo 12 and 15 are also included.
