Notes.

(a)

ID from the QSO MUSEUM sample.

(b)

Systemic redshift of the quasar evaluated from the peak of the C IV line, correcting for the expected shift as estimated by Shen et al. (2016). The intrinsic uncertainty on this correction is ∼415 km s−1 and dominate the error badget (Δz ≈ 0.007).

(c)

Noise level at the center of each map.

(d)

Effective area assumed in this work and defined above the 3 times the central noise.

(e)

Exposure time on source.

(f)

Range of values of the opacity at 225 GHz for each target.

(*)

Systems with a radio-loud central or companion quasar.

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.
