Intensity profile of the detached layer at 21:05 UT. The black vertical bar shows the position of the terminator. The blue vertical solid line shows the position of the maximum intensity of the cloud detached layer with the full width at half maximum between the two dashed blue vertical lines. On the right side, a cartridge of Mars with the detached layer in the cross-section where the intensity profile was taken shows a thin cloud system emerging with a width similar to the point spread function (rather than a higher cloud located closer to the terminator) with an actual apparent width of 3.4 pixels (see text).
