Abstract
The advent of more precise measurements of distance estimates for some objects (Bayesian estimates for filaments, trigonometric estimates for masers) permits a better comparison of their relative locations, and a comparison with a most recent spiral arm model fitted to the diffuse CO 1-0 gas. Our results support the idea that some ‘bone-like’ filaments, greater than 10 pc (labeled elsewhere as ‘bones’, ‘mst’, ‘herschel’) and smaller than 100 pc, are observed near the potential minimum of the Scutum spiral arm (bone-like filaments are offset outward from masers by about 200 pc).
