Temperature map from the HCN/HNC ratio. The color-scale shows the temperature map derived from the integrated intensity ratios of the HCN(1−0) and HNC(1−0) line following Hacar et al. (2020). The black contours show the GLOSTAR cm continuum emission from 20 to 100 mJy beam⁻¹ in steps of 10 mJy beam⁻¹. The 3.6 mm continuum positions are marked as five-point stars. A linear scale-bar is shown at the left, and the six main regions A to F are labeled.
