Notes. The Gaussian fit parameters (in TMB scale) refer to the spectra extracted at the emission peak: α2000 = 03h29m03.s75, δ2000 = +31°16′03.′′8. (a) Spectral parameters from the Cologne Database for Molecular Spectroscopy (Müller et al. 2001, 2005) for all the species, with the exception of those of the H2CS isotoplogues, derived from the Jet Propulsion Laboratory (JPL Pickett et al. 1998), and those of NS+, from Cernicharo et al. (2018). (b)Possible contamination with 13CCS emission at 82123.376MHz (Eu = 22 K, 2 = 0.7 D2). (c) The C33 S(2–1) line consists of 6 hyperfine components (Bogey et al. 1981; Lovas 2004; Müller et al. 2005) in a 9 MHz frequency interval. The line with the highest 2 is reported (see Fig. 5). (d)Lines blended at the present spectral resolution (2 MHz). Possible contamination with CH3OH emission at 206001.30 MHz (Eu = 317 K, 2 = 10.2 D2). (e) Contaminated by SO(45 –34) high-velocity emission. (f)The 9/2–7/2 Ω=1/2 line consistsof 3 hyperfine components (Lee et al. 1995) in a 0.6 MHz frequency interval. The line with the highest 2 F=11/2–9/2 is reported (see Fig. 5). We give (g) 3σ as the upper limit.
