Notes.

^(a)

Flux density and estimated errors.

^(b)

r and PAs are the polar coordinates of the component’s center with respect to the core. The PAs are measured from north through east. σ_r are estimated errors in the component position. σ_PA are estimated errors in the PA of the component.

^(c)

The FWHM of the radius of the circular Gaussian component and estimated errors in the component size.

^(d)

The VLBA 43 GHz data.

^(e)

The GMVA 86 GHz data.

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.
