Notes.

(a)

Weight scheme associated to each candidate, as explained in Sect. 3.2.

(b)

3-σ upper limits of weighted average for each bin (Eq. (16)).

(c)

CLEANing method used in CASA to obtain final image.

(d)

Maximum value from a box in the stacked images.

(e)

rms errors from Eq. (6).

(f)

S/N = Fluxpeak/rms.

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.
