Spectra observed towards L1455-IRS1 (see Table A.3 in TMB scale). Species, transition, and upper level energy are reported in each panel. The vertical dashed line stands for the source systemic velocity measured using the C18O(2–1) line (+4.7 km s−1). In the 13CN(2–1) spectrum the velocity scale is centered on the brightest (8 D2) hyperfine component (vertical blue line) at 217467.1 MHz; the vertical red line indicates the offset in velocity of the fainter component (5 D2 at 217467.1 MHz). In the 13CS(5–4) spectrum the velocity scale is centered on the brightest (38 D2) hyperfine component (vertical blue line) at 231220.7 MHz; the vertical red lines indicate the offset in velocity of the fainter components (21 D2 at 231220.7 MHz; 17 D2 231220.6 MHz; 1 D2 at 231220.5 MHz). In the CCD(3–2) spectrum (fourth row) the velocity scale is centered on the brightest (2 D2) hyperfine component (vertical blue line) at 216428.3 MHz; the vertical red line indicates the offset in velocity of the fainter components (0.7 D2 at 216428.8 MHz). Lower panel: In the CCD(3–2) spectrum the velocity scale is centered on the brightest (3 D2) hyperfine component (vertical blue line) at 216372.8 MHz; the vertical red lines indicate the offset in velocity of the fainter components (1.9 D2 at 216373.3 MHz; 1.4 D2 at 216373.2 MHz). In the DCN(3–2) spectrum the velocity scale is centered on the brightest (35 D2) hyperfin component (vertical blue line) at 217238.3 MHz; the vertical red lines indicate the offset in velocity of the fainter components (20 D2 at 217238.6 MHz; 16 D2 at 217238.3 MHz).
