(a) Histogram of differences in gravity obtained by relative gravimeters S/N 581 and 705. The differences correspond to those between red and blue data points in Fig. 4 that were obtained simultaneously. The solid and dotted curves denote the fit of two types of probability density functions (Laplace and Gaussian distributions). The variances for the fitting were 5.8 for the former and 30.9 for the latter. (b) The same as for (a) but for all three gravimeter pairs (581–705,705–876 and 581–876). The variances for the fitting were 38 and 119 for the Laplace and the Gaussian distributions, respectively.
