In order to select the most suitable method of harmonic analysis for tidal variation of gravity, and to check the methodical difference in the tidal factor-G, the three methods of analysis, the Darwin's, Doodson's and Lecolazet's, were applied to the data obtained with the Askania gravimeter at two stations, Kyoto and Matsushiro.
Comparing the results in three cases with each other, the obtained values of G show the maximum difference of 10 percent. From the present treatment, it is provisionally concluded that the Doodson's method is preferable in case of monotonous drift and the Lecolazet's is suitable for the case of irregular drift.
