Coefficients for the MoMo model to predict the vTEC in the Mars’ ionosphere. These coefficients are given for different ranges of solar longitude (Ls) and the two hemispheres. The number of data per range of SZA and the associated RMS of the differences between the vTEC predicted by the model and the observed vTEC are reported in the last columns.

|North||45° ≤ Ls < 225°||3.284||2.624||1.564||159,997||983,540||0.10||0.05|
