Notes. 

(a)

Peak flux density (in Jy/21.2″-beam), total flux, FWHM along the major and minor axes, and position angle (east from north) of the fitted Gaussian.

(b)

Mean source size, equal to the geometrical mean of the major and minor FWHM.

(c)

Type of source based on the associations found in the SIMBAD database (see Table 3).

(d)

Source found in the SIMBAD database within the FWHM ellipse, its type in parentheses, and its distance to the peak position. 2MASS was abbreviated to 2M. The abbreviated references in square brackets and the source types in parentheses are defined in SIMBAD.

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.
