Integrated DCO⁺(1 – 0) contours in yellow on H¹³CO⁺(1 − 0) emission in color. The integration regimes for the two molecular transitions are from −7 to 3 km s⁻¹. The yellow DCO⁺ contours are from 50 to 500 mJy beam−¹km s⁻¹ in steps of 50 mJy beam⁻¹ k ms⁻¹. The black contours show the GLOSTAR cm continuum emission from 20 to 100 mJy beam⁻¹ in steps of 10 mJy beam⁻¹. A linear scale-bar is shown to the left, and the six main regions A to F are labeled and marked by five-point stars.
