Superconducting Gravimeter Calibration by CoLocated Gravity Observations: Results from GWR C025

Figure 5

SG/AG comparison experiment at Conrad observatory in December 2008 (upper panels) and June 2011 (lower panels). (a) Calibration factor plotted against the number of data pairs used in the linear adjustment. No (black) or linear (red) drift has been adjusted. (b) Calibration factor (black) and RMS of the residual (grey) plotted against the polynomial degree selected for AG drift adjustment. The ±1‰  error range is displayed as grey box.
