An HXT image in the LO channel at 1992 January 13 17:27:40–17:28:20 UT. The image is square‐root scaled. The thin contour shows the 7.5% contour of the M1 emission, and the thick contour shows the integration boxes. One box was chosen to enclose both footpoints, while the other was chosen to enclose the loop top. The sizes of the individual boxes were chosen to enclose the bulk of the M1 emission emanating from the enclosed sources.
