Huber Regression fits to Martian (a) and Terrestrial (b) TEC as a function of SZA for the four different SZA regions. Panel (a) includes an entire MY of data and shows both the Huber (magenta) and standard linear (black) fits. Panel (b) shows a single MY, season, and location region for Earth, identifying both inliers (grey) and outliers (black). Panels (cf) show the differences between the Huber Regression fits and measured TEC at dawn (Panels (c) and (e)) and dusk (Panels (d) and (f)) at Mars (Panels (c) and (d)) and Earth (Panels (e) and (f)). In each of these panels the outliers are plotted in black and the inliers in grey, while the median of all differences is shown by a vertical line
