Notes.

(a)

Frequency of the observed transitions in TMC-1 assuming a local standard of rest velocity (vLSR) of 5.83 km s−1 (Cernicharo et al. 2020).

(b)

Integrated line intensity (in mK km s−1).

(c)

Line width at half-intensity derived by fitting a Gaussian function to the observed line profile (in km s−1).

(d)

Antenna temperature (in millikelvins).

(e)

FS10 and FS8 refer to cases with only data from the set of observations with a frequency throw of 10 MHz and 8MHz, respectively.

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.
