Notes. Information of the different line transitions targeted by our ALMA observations. Errors in Cols. 4 to 8 indicate the 1σ uncertainty. Upper limits are set at the 3σ level. Fluxes measured in the clean component map using natural weighting.

^(a)

The observed frequency as computed assuming a Gaussian profile. The value in parenthesis refers to the rest-frame line frequency.

^(b)

The adopted redshift is z = 1.027 (D_L = 6828.3 Mpc).

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.
