Dust continuum emission images from: Herschel PACS (70 and 160 μm) and SPIRE (250, 350, and 500 μm); JCMT SCUBA-2 (450 and 850 μm); and either IRAM MAMBO/MAMBO-2 (1.2 mm) or CSO Bolocam (1.1 mm) instruments. The color scale is in units of Jy beam⁻¹. The location of the methanol masers detected with the VLA are indicated by the black crosses. The Galactic names of the GLOSTAR sources are indicated at the top of the bottom-left panels. The beams are shown at the bottom-left corner of each panel. Saturated pixels are shown in gray.
