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 either unpolarized or variable are filled with “...”. Sources with both stable ml and χ are marked in bold face. 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 during which the source was observed; (4) the number of sessions during which significant ml was detected; (5) the average value of Stokes I; (6) the average value of χ and (7) the standard deviation of χ over the entire data set.
