Table 2 The mean values and standard deviations from the mean of RMS misfit errors between the measured satellite data and 5th degree polynomial main field models (January and December), and RMS differences between the SV data (January–December) and data obtained from the 2nd degree polynomial SV models for years 2001–2005.
