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.
