Abstract : The operating instructions, as well as the mathematical and astronomical background, are given for a versatile computer code for calculating time series of earth tidal gravity and tilt. The contributions of ocean tidal loading can be simply incorporated if harmonic coefficients of the loading are available. The accuracy of the astronomical portion of the tide should be better than 1 percent. The accuracy of the astronomical portion of the tide should be better than 1 percent. A number of output and printer-plotting options are easily exercised. The self-contained program was written for the CDC 6600 computer in FORTRAN Extended. (Author)
