Notes. The second col. shows the observation date, the corresponding Carrington rotation number and the position of the lower-left corner of the studied area. The fourth and the fifth cols. are the heliographic coordinates of the start and end point of the test-box, respectively. The sixth col. expresses the chirality of the filament. The seventh col. shows the absolute value of the magnitude of the gradient at a distance of 10 Mm from the axis of the test box. The eighth col. indicates agreement/disagreement between gradient of the axial velocity and chirality. The ninth and last cols., shows the values of divergence (positive values) and convergence.
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.
