G14 SNRs confused with H ii regions. Shown for each region are two-color images with GLIMPSE 8.0 μm (for G20.4+0.1, G21.5−0.1, G23.6+0.3, and G54.1+0.3) or WISE 12 μm data (for G59.8+1.2 and G65.8−0.5) in cyan and THOR+VGPS 21 cm continuum data in red. The central positions are taken from the G14 catalog, and the image dimensions are three times the G14 SNR diameters. As in Fig. 1, the candidate SNRs are enclosed by green circles and known or candidate H ii regions by white circles. Red dotted circles show the expected position and size of the G14 SNRs that are confused with H ii regions.
