[bug #62702] Clumps on strong gradients of larger galaxies become too large

[Mohammad Akhlaghi]

Follow-up Comment #3, bug #62702 (project gnuastro):

I was able to start testing the hypothesis below by making the following
figure: at the top you see the plot showing how the azimuthal angle changes as
we come down from the brightest pixel of the small clump.

(file #55002)

The bottom images show the convolved image on the left and the azimuthal image
on the right.

This shows that indeed, for the inner pixels of the small clump, we cover the
full azimuthal angle range of -180 to 180 degrees. But as we progress (beyond
roughly 25 pixels), this coverage decreases and this is the location that we
are dominated by the large galaxy and should stop growing the smaller clump.

Work on this test is on-going in the

'segment-clump-on-wing' branch of my development repository].
