Notes. For each entry the upper row corresponds to 4.85 GHz and the lower to 8.35 GHz. The rows corresponding to frequencies at which the source was found to be variable are filled with “...”. The entry in each column is as follows: (1) the source survey name; (2) the period that the source was observed; (3) the number of sessions that the source was observed; (4) the average value of Stokes I over the entire data set; (5) the number of sessions that the mc measurements were corrected with method A; (6) the average value of mc, corrected with method A; (7) the standard deviation of mc, corrected with method A; (8) the number of sessions that the mc measurements were corrected with method B; (9) the average value of mc, corrected with method B; (10) the standard deviation of mc, corrected with method B, over the entire data set.

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.
