Notes. Columns from left to right: (1) Component label, (2) observing day in 2017, (3) linear polarization flux density (P), (4) EVPA (χ), and (5) degree of polarization (m). For all quantities in this table, the quoted “errors” are the intra-component dispersions computed as the standard deviation of pixel-by-pixel values within the component area, unweighted by polarized intensity. These numbers measure spatial non-uniformity within the component and are not systematic or thermal errors. Component P3* averaged values listed here are significantly affected by the internal substructure found in this component.
