Infrared images (color scale and white contours) of the environment of the VLA-detected methanolmasers toward DR20. Top-left panel: three-color map constructed using Spitzer 3.6 μm (blue), 4.5 μm (green), and 8 μm (red) images. Other five panels: infrared emission for each of the Spitzer bands. The nth white contour is at , where S_max is the maximum flux shown in the color bar (MJy sr⁻¹) for each panel, n = 0, 1, 2..., and p is equal to 30%. The green crosses mark the positions of the maser features seen in B-array configuration maps. The Galactic coordinate name of the GLOSTAR source is indicated at the top of the top-left panel. The beams are shown at the bottom-left corner of each panel. Saturated pixels are shown in gray. The same figure for all sources is provided in Appendix A.
