Example of the core-averaged, background-subtracted DCN (3–2) single-type spectra for six cores in the young protocluster G338.93. The associated continuum core number is given in the top left of each panel (the core numbering is taken from Louvet et al. 2023). The core V_LSR (V) and velocity dispersion (σ) in units of km s⁻¹ from the HSF fit are given in the top right. The line fit parameters for each core are also presented in Table 3. The pink-shaded region represents the part of the spectrum used to estimate the MAD noise.
