Notes. 

(1)

The spatial resolution of observations was  ~0.6″ (FWHM).

(2)

Corrected for the instrumental spectral broadening by subtracting in quadrature the spectral resolution.

(3)

Corrected for the instrumental beam smearing by subtracting in quadrature the PSF FWHM.

(4)

No correction for instrumental beam smearing, the spectroastrometry technique enables to make distances measurements down to  ~1/10 of the spatial resolution (see text).

(5)

Masses are in unity of log (M/M⊙).

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.
