4 note(s) found in NED.

Re:1936-155
4.2 Previously identified inverted-spectrum sources
B1936-155: this blazar has a redshift of 1.657 (Jauncey et al. 1984).
It is classified as a high-peaking GPS source (Tornikoski et al. 2001).
The spectrum in Fig. 5 has a slightly convex shape at the maxima but
there is variability at all radio frequencies and the lower envelope is
flat.

Re:VSOP J1939-1525
The image found in VLBA2cm2 has an extra component to the east of the
core.

Re:3EG J1937-1529
3EG J1937-1529. J1935-1602, plausible, and J1939-1525, likely, both lie
in this elongated error box. Our analysis does not support the
previously claimed counterpart J1941-1524.

Re:PKS 1936-15
PKS 1936-155 (OV-161; Fig. 1q).--This is a blazar with high
optical polarization (Fugmann & Meisenheimer 1988) and a high redshift of
z=1.657 (Jauncey et al. 1984). It has a very steep spectrum between 1.4 and
2.7 GHz and a flat spectrum between 2.7 and 5.0 GHz, and probably to 8.4 GHz
(Quiniento & Cersosimo 1993; Impey & Tapia 1990).
VLA 6 cm observations showed the source to be unresolved, with a flux density of
0.72 Jy (Neff, Hutchings, & Gower 1989). Our VLBI image shows a single component
0.6 mas x 0.5 mas in size, elongated in the north-south direction, with a flux
density of 0.97 Jy. A slight extension to the southeast can be seen from the
map. The compact core has a brightness temperature of 4.7x10^11^ K, compared
with a lower limit of 2.5x10^11^ K from the 22 GHz survey (Moellenbrock et
al. 1996).
