| [S II] 673 nm | 1.6 * 104 | 14(39%) | 5(14%) | 6(17%) | 12(33%) | 3(8%) |
| [N II] 658 nm | 8.0 * 104 | 13(36%) | 0(0%) | 0(0%) | 12(33%) | 2(5.5%) |
Notes. Critical densities are from Giannini et al. (2019). The velocity separation among the different components has been defined as follow (see text): Narrow Low Velocity Component (NLVC): |Vp| < 30 km s−1, FWHM < 55km s−1, Broad Low Velocity Component (BLVC): |Vp| < 30 km s−1, FWHM > 55 km s−1, High Velocity Component-Blue (HVC-B): Vp < −30 km s−1, High Velocity Component-Red (HVC-R): Vp > +30 km s−1.
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.
