J1150-0023.-No detection on space baselines, and no image is given. The core
region contains about 0.13 Jy in a component <0.6 mas. See VLBApls for a model
of the extended emission.
4.3 Candidate inverted-spectrum sources
B1148-001: the spectrum of this distant (z = 1.983) quasar is flat.
J1150-0023 (PMN J1150-0024): referred to as a GPS source by Jauncey et
al. (2003), however it would appear any peak lies below 350 MHz and so
we classify it here as a CSS source. Slee (1995) gives 80 and 160 MHz
flux densities of 5 Jy and 3.0 Jy respectively. The snapshot VLBI
observation of Fomalont et al. (2000) yielded a core-jet morphology,
with the jet extending over ~30 mas form the core.
1148-001: Kellermann et al. (1971) reported a compact
structure of this source at parsec scales, and interplanetary
scintillation observations suggested three compact components
at kiloparsec scales (Venugopal et al. 1985). The RRFID images
show a jet to the southwest turning to the south beyond 20 mas
of the core, extending up to more than 40 mas at 2.3 GHz, and
with a bright component at 3.2 mas, P.A. = -119^deg^, and a
more extended one at 10.9 mas, P.A. = -123^deg^ at 8.5 GHz.
Our image from 1998 November reports a conspicuous jet
extending to the southwest over 20 mas, with one component
located at 2 mas from the core and the other at 5 mas from
Q1148-0007 (PKS 1148-00, z_em_ = 1.982)
This object has been studied by SBS and YSB, who found C IV
absorption at z_abs_=1.4669 and 1.9861. SS studied this object in
the range 5148 - 8947A and found no identified absorption lines.
The unidentified line they report at 6280.0A is most likely a weak
atmospheric O_2_ band. At the position of their line at 8854.8A,
we observe the equivalent width W_obs_=0.24+/- 0.23, in contrast to
their value W_obs_=1.37+/- 0.17. We find no new absorption systems
in our spectrum.
