Filament 7 is a confirmed bone candidate, with a quality grade of “B.” There is a slight break in the extinction feature around \(l=4^\circ\), so it weakly satisfies criterion 1. It moderately satisfies the other five criteria, though we note that we were unable to confirm contiguity in velocity space using lower density gas tracers, as it was outside the coverage range of both GRS and ThrUMMS. It does, however, express contiguity as traced by higher density gas from the HOPS and MALT90 surveys. It lies on top of the Scutum-Centaurus fits to CO and HI , but its velocity gradient is slightly angled with respect to these fits, suggesting it could be a potential spur of this arm.
