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

Figure 6

SG/CG5 comparison experiment at Conrad observatory (July 13, 2010 to September 22, 2010). (a) Calibration factor plotted against the number of data pairs used in the adjustment and for different drift polynomials. As best choice, a drift polynomial of degree 8 has been selected (dashed red line). (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.
