Notes. In case of blending, lines with stronger CDMS/JPL intensity are listed in the left column, and the possible weaker blended transitions in the right column. Without any digital annotation indicates that the lines are detected in both IRS1 and MM1, especially showing absorption or an (inverse) P-Cygni profile towards IRS1-peak. “^1.1” denote the lines being detected in IRS1 only, especially showing absorption or an (inverse) P-cygni profile towards IRS1-peak. “^1.2” denote the lines being detected in IRS1 only, especially showing pure emission towards IRS1-peak. “^1.3” denote the lines being detected in IRS1-mmS only, but without clear detection in IRS1-peak. “^2.2” denote the lines being detected in both IRS1 and MM1, especially showing pure emission towards IRS1-peak. “^2.3” denote the lines being detected in both IRS1 and MM1, but without clear detection in IRS1-peak. “³” denote the lines being detected only in MM1.

^(a)

Tentative detections (intensity ~3σ rms) are marked with “*”.

^(b)

Unidentified lines are denoted as “UL”, and possible transitions are given.

^(c)

“A(E)A(E)” indicates 4 types of transitions are possible for a certain line: AA, EE, AE, EA.

^(d)

Lines with † are imaged in Fig. 3.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
