Locations of methanol sources detected with the VLA (blue circles), overlaid on a Herschel SPIRE 500 μm continuum image of the Cygnus X region (grayscale). The mosaic was generated by Cao et al. (2019) from data obtained as part of the HOBYS (Motte et al. 2010; Hennemann et al. 2014) and Hi-GAL projects (Molinari et al. 2010). The region outlined in green represents the area mapped with GLOSTAR. A few well-known star-forming regions and radio continuum sources (Downes & Rinehart 1966) are labeled in yellow.
