Imageof the λ ≈ 3 mm continuum emission from the central region of NGC 4945 (1″ corresponds to a projected linear scale of ≈19 pc). The mapis based on the line-free sky frequencies of 88.27–88.38 GHz and 88.54–88.70 GHz in the H12 C14N window, 85.60–86.01 GHz and 86.28–86.42 GHz in the H12C15N window, 97.35–97.72 GHz and 98.01–98.24 GHz in the CS window, and 100.15–100.46 GHz in the continuum window (see Sect. 2). The beam size is 2.′′55 × 1.′′ 34 (0.1 Jy beam−1 is equivalent to ≈6.8 K) with a position angle of 44°.2. Contour levels are 0.5, 1, 2, 5, 10, 20, 40, 60, and 80% of the peak flux density of 96 mJy beam−1. The restored beam is shown in the lower left corner. In view of the limited extent of the emission, no primary beam correction has been applied.
