Average profiles of Ca ii IR at 854 nm. Top: average profiles of the full FOV (black), field-free (red), and magnetic locations (blue). Bottom: difference between the profiles of the full FOV and the field-free locations (red solid) and difference between magnetic and field-free locations (blue dash-dotted). The dotted vertical lines denote the locations of line blends, and the dashed vertical lines illustrate an asymmetry in the intensity differences.
