Left: G-band contrast IC of one of the MHD snapshots, saturated at 1.5. Dotted blue lines: borders of regions where 1 hG <B0 < 1 kG. Solid blue lines: regions where 1 hG <B0 < 1 kG and IC ≥ 1. Solid red lines: regions where B0 ≥ 1 kG. Middle left: same as left panel, but image degraded with a PSF_50cm_430. Middle Right: B0 corresponding to left panel. Right: B0 convolved with a PSF_50cm_06. Dotted green lines denote contours of features identified in images in the left and middle-left panels, respectively, assuming α = 1.5; solid green lines denote borders of a subset of identified features whose average field value is between 1 hG and 1 kG.
