Mean brightness temperature Tb at 15 GHz based on (1) except for [HB89] 1219+044 (2), brackets refer to the median.
Tb at ~ 8 GHz, mean Tb based on (1) and the median in brackets for PMN J0948+0022; 1H 0323+342 from (3), FBQS J1644+2619 from (4), [HB89] 1219+044 from (5).
Projected linear size from VLA observations; for SBS 0846+513 and PKS 1502+036 the major beam axis of the highest resolution VLA observation from (6) and (7), respectively, was used as a conservative upper limit; Reference (4) for 1H 0323+342, PMN J0948+0022, FBQS J1644+2619; Reference (8) for [HB89] 1219+044.
References for 1H 0323+342 (3, 9), SBS 0846+513 (6, 9, 10), PMN J0948+0022 (11, 9), PKS 1502+036 (7, 9), and FBQS J1644+2619 (4).
Variability index for 1H 0323+342, SBS 0846+513, PMN J0948+0022, and PKS 1502+036 at 4.85 and 8.35 GHz, respectively, from (9); PKS 2004−447 at 5.5 and 9.0 GHz.
Variability index at X-ray energies from 0.3–10 keV for 1H 0323+342 (1), SBS 0846+513 (10), PMN J0948+0022 (1), and PKS 1502+036 (7); 0.5–10 keV for PKS 2004−447 (12); For PKS 1502+036 all flux measurements were consistent within the given uncertainties, yielding a negative value.
