Fig. 1.


False-color GLIMPSE survey mosaic (Benjamin et al. 2003; Churchwell et al. 2009) of the Sagittarius Arm structure. The three white contours show the intensity of 12CO emission (10, 31, and 100 K km s−1) from Dame et al. (2001) integrated over the velocity range vlsr = 5–30 km s−1. Symbols mark the YSO groups, masers, and the Morgan OB associations (reanalyzed with Gaia) that make up the structure. Smaller boxes and circles indicate greater distances, and arrows indicate proper motions.
