HNC (1–0) channel map. The observational velocity resolution is 0.21 km s−1; here, we smooth the data to 0.42 km s−1. The contour levels start from 4σ and increase in steps of 10σ (1σ = 0.008 Jy beam−1). The cyan crosses indicate the position of cores 1, 2, 4, and 10, as labeled in Figure 1. The synthesized beam is given in the bottom right.
