Details of the cases shown in Figs. 3, 7, and 10 using the NM datasets. Left: Ca II 854.2 nm intensity filtergrams at −1.755 Å. The yellow rectangles superimposed over the small and large concentrations enclose the regions shown zoomed-in on the right-hand side. Right: magnetograms at −0.39 Å and B_∥ estimates for each Δλ and Δt. The plus symbols (+) mark the pixels shown in Fig. 13. Pink and black contours enclose each case and the pixels with two-lobed V profiles inside them, respectively. Major tick marks represent 1″.
