Illustration of the alignment procedure. The panels show the sequence of 101″ × 101″ images of the alignment chain, that is, AIA 193 Å → AIA 131 Å → AIA 1600 Å → HMI magnetogram. In each image the contours of the respective image following in the chain are overplotted. The Hi-C 193 Å image is aligned with the AIA 193 Å channel and its contours are overplotted on the HMI magnetogram. The magnetogram contours are at −100 G (white) and −300 G (black). The other contours show the percentages of the maximum brightness in the respective channel (numbers with the contour lines).
