Notes. Columns (2) and (3) give the Galactic longitude range and latitude range of the filament regions, respectively. Column (4) gives the line-of-sight velocity range of each GMF as defined in Ragan et al. (2014). Columns (5) and (6) give the kinematic near distance from us and the Galactocentric distance, respectively.(a) As in Ragan et al. (2014). (b)The distances are not taken from Ragan et al. (2014) but have been recalculated using the more recent spiral arm model by Reid et al. (2019).

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.
