\label{fig:Candid5_pos_pos}: Plane of the sky map integrated between 35-55 km/s, the approximate velocity range of the Scutum-Centaurus arm in the region around BC\_18.88-0.09. A trace of BC\_18.88-0.09, as it would appear as a mid-IR extinction feature, is superimposed on the CO emission map.The black dashed line indicates the location of the physical galactic midplane, while the solid black lines indicate ± 20 pc from the galactic midplane at the 3.7 kpc distance to BC\_18.88-0.09, assuming the candidate is associated with the Dame et al. (2011) \citet{Dame_2011}  Scutum-Centaurus model. The correlation between BC\_18.88-0.09's mid-IR extinction feature and Scutum-Centaurus's most intense CO emission hints that BC\_18.88-0.09 may be a spine of Scutum-Centaurus as traced by lower density CO gas
