The method of least squares collocation was used for gravity vector estimation from torsion balance measurements in southern Ohio. The results were dependent on the covariance function used and on the selection of a proper signal to noise ratio. Here a standard deviation of the noise of 10 EU (10-9 s-2) gave the best results. Expressed in terms of standard deviations of observed minus predicted differences, the best results were 0.4 arc sec for deflections of the vertical and 2 mGal for gravity anomalies. This compares to signal standard deviations of 4 arc sec and 22 mGal for deflections and gravity anomalies, respectively. ¿ American Geophysical Union
