Comparison of footpoint position in AACGM coordinates for TA15n versus the T89, T96, T01, T04, and TA15b. (a–j) Magnetic local time (MLT). (k–t) Magnetic Latitude (MLAT). The black diagonal line represents the ideal scenario where both models agree perfectly. The red dashed lines indicate a deviation of ±1 (hour for the MLT plots and degree for MLAT plots). The pink dashed line marks a 5° difference in latitude, corresponding to the approximate distance of 1 hour of MLT at 70° latitude. The solid red line represents the mean value. For each plot the mean bias error (MBE) and the root mean square error (RMSE) are indicated.
