| Column 1: source name. Column 2: side of the source on which the spectral aging was determined. Column 3: the distance from the hotspot. The estimated error is 0.5 arcsec. Column 4: the estimated break frequency. Column 5: the estimated hot spot advance speed assuming the magnetic field is equal to 0.25 the averaged equipartition value given in Table 2. Column6: the estimated hot spot advance speed assuming the magnetic field is equal to the averaged equipartition value given in Table 2. The last row for each side gives the weighted mean velocity. |
