Examples of edge cases identified by Sutra. The top row shows a single filament from the Aquila molecular cloud. The middle row shows a single beam element from the filament. Panel (A) shows a beam element corresponding to a low-contrast filament. Panel (B) shows a beam element with overlapping filaments, which lead to kinks in the central maxima. Panel (C) shows a filament with overlapping low-intensity structures that lead to a poor Plummer model fit.
