2.3 A closer look at a loop leg
Figure 17: The loop (black),
background (white) areas, and a cut across the loop.
Right the profiles in the two TRACE bands.
Overplotted with a dashed line is the 173 Å intensity profiles
that would be expected from a circular cross-section
with constant density and a width of 8.
Note the small difference in the loop and background signal,
in particular for the 195 Å band.
