Notes. Velocities were calculated only when the characteristic W-shape was clearly identified by eye. In the third column of the table, lines 1, 2 and 3 refer to Ca λ8498, 8542 and 8662, respectively. Vblue, Vred are the blue and the red component velocities respectively of the W shape. Ashock is the shock amplitude derived by Vblue − Vred. The FWHM of blue (σblue) and red (σred) components are also listed. All values are given in (km s−1). Stars are ranged by increasing periods from top to bottom.
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.
