Line-of-sight magnetic flux inferred for the three QS regions. Top row, from left to right: LOS magnetic flux PDFs for north region, disc centre, and east-limb dataset. The positive tail is shown in solid blue, and the negative one is folded to positive values and shown by the orange dashed line. Middle panels: same representation for Network patches (see text for their definition) and bottom panels: for the rest of the magnetic signals. Top-left panel: includes two grey lines to show the LOS magnetic flux above 70° heliocentric angle.
