Notes.

(a)

Modified Julian day;

(b)

Number of 12 m antennas in the array;

(c)

Average precipitable water vapor in the atmosphere during the observations;

(d)

Parallactic angle;

(e)

Flux densities of the NE and SW images, respectively. We adopt a conservative absolute flux accuracy of ∼20%;

(f)

Flux-density ratio between the NE and SW images, the number in parenthesis gives the uncertainty on the last digit;

(g)

Polarization ratio, as defined in Eq. (2);

(h)

Spectral index difference between the NE and SW images: Δα = αNE − αSW;

(i)

rms noise level of the spectrum between 295.0 and 295.4 GHz (i.e., a line-free region in the spectral window centered on the redshifted H2O transition), in % of the continuum level of the SW image, at the native spectral resolution of ∼0.6 km s−1.

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.
