Notes.

^(a)

Date of observation;

^(b)

GMVA elements with good data after calibration, imgaing and flagging: Effelsberg (Ef), Onsala (On), Metsähovi (Me), Plateau de Bure (PdB), Very Long Baseline Array (VLBA, the eight stations equipped with 86 GHz receivers) image noise level;

^(c)

peak flux density of the image;

^(d)

total flux density;

^(e)

major axis, minor axis, and position angle of the restoring beam.

^(f)

The flux density might be underestimated by about 22% (see Sect. 2.1).
