Note. The columns are as follows: (1) source name (B1950); (2) core shift between low and high frequencies; (3) low frequency; (4) high frequency; (5) reference for core-shift measurement; (6) core-position offset Ω_rν calculated using columns (2)–(4) and k_r from Table (4); (7) core position from the jet base at the high frequency assuming k_r from Table 4; (8) as column (7) but for low frequency.
