Notes. Reference positions used to derive millimetre offsets for each source are those taken from Do10, Crowther et al. (2006a), Clark et al. (2010), Negueruela et al. (2010) and from the recent FLAMES Wd1 survey (Clark et al., in prep.). As described in Sect. 3.1.1, the acronym “LAS” corresponds to “largest angular size” and is used to report dimensions for non-Gaussian sources.
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.
