a) Same as Fig. 1a but for the source Do321P2. The contour levels start at 0.3 K km s-1 and increments are 1.0 K km s-1. b) NH3(1, 1) radial velocity (color map) structure. The velocity field is shown after subtracting the mean radial velocity ⟨ VLSR ⟩ = 6.905 km s-1. The intensity peaks are labeled as in Table 1. c) NH3(1, 1) intensity map as in panel a). Open circles of different colors mark Class I (red), intermediate type (yellow), Class II (blue), and Class III (cyan) YSOs taken from Tsitali et al. (2010). The SCUBA sources from Visser et al. (2002) are marked by magenta: SMM7 is a starless core, whereas SMM1 and SMM2 are protostars that coincide with IRAS 19180+1116 and IRAS 19180+1114.
