Notes. Columns are: (1) observing epoch; (2) the duration of observation; (3) the effective number of data points; (4) and (5) the mean flux density and the rms flux density; (6) the modulation index; (7) the mean modulation index of calibrators; (8) the relative variability amplitude of IDV; (9) the characteristic timescale in days (variability types: Type II means an IDV timescale <2 days while Type I means an IDV timescale >2 days); (10) the reduced chi-square.
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.
