Table 2. Summary of the different models produced to test the FTMM algorithm and their distinguishing parameters. The models are: ‘Standard’, which is the base model for comparison; ‘12hr’, which selects data within a 12 hour local window centred on midnight; ‘SM ’ performs the average over each orbit in Solar Magnetic Coordiantes; ‘C.I. ’ uses only Comprehensive Inversion models to subtract non-magnetospheric fields; and ‘20s ’ uses double the data sampling rate of the other models. ‘GEO ’ refers to the Earth-fixed Geographic frame; and ‘Reference ’ indicates that the TDS-1 reference models were used to subtract the core and lithospheric fields (but the Comprehensive Inversion ionospheric-field model is used in all cases).
