Core V_LSR (left) and DCN (3–2) linewidths (right) estimated from the DCN (3–2) fits to the continuum cores towards examples of a young and an evolved protocluster G338.93 (top) and G333.60 (bottom), respectively. The circles and stars represent the detected cores with mass estimates below and above 8 M_⊙, respectively, with the colour scale displaying the fitted parameters from the DCN (3–2) fits (left: core V_LSR, right: linewidth). The core V_LSR is the centroid velocity of the DCN (3–2) fit minus the cloud V_LSR (taken as −62 km s⁻¹, and −47 km s⁻¹ for G338.93, and G333.60, respectively). The grey contours are the 4σ level of the DCN (3–2) moment 0 map. In the right panels, the positions of cores without a DCN (3–2) detection are marked with a black cross and with a black star for cores with a mass estimate below and above 8 M_⊙, respectively, and green triangles and stars represent cores with a complex-type DCN (3–2) spectra, with a mass estimate below and above 8 M_⊙, respectively.
