Notes. (a,b)See Table 2.

(c)NO lines were blended with a CH3OH line and hence only an estimate of the upper limit on the peak temperature could be established. For this, we assumed that the NO lines at ~351050 and ~350690 MHz have similar emission strengths because of their identical Eup and very similar Aij values.

(d)Multiple detected lines very closely spaced in frequency resulting a non-gaussian profile. No Gaussian fitting was done. Emission upper limits were determined from peak TMB values.

(e)CO line and its isotopes showed self absorption. Multiple Gaussian line fitting was not performed in this study. Hence, no Gaussian fitting was done to these lines.

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.
