Notes. Hyphens indicate that no data were available.

(a)

Redshift from NED.

(b)

Mean brightness temperature Tb at 15 GHz based on (1) except for [HB89] 1219+044 (2), brackets refer to the median.

(c)

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).

(d)

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.
