Notes for object [HB89] 1313-333

6 note(s) found in NED.


1. 2008ApJS..175..314D
Re:VSOP J1316-3338
J1316-3338.-The core is 0.3 mas in size. There is extended structure to the
southwest and west.

2. 2002ApJ...579..136T
Re:[HB89] 1313-333
B1313-333, a possible counterpart of 3EG J]314-3431 (z = 1.210, QSO,
Figs. 4b and 11) .-This source is very variable at the high radio
frequencies. The EGRET detections with (TS)^ 1/^2 >= 2 have been
made at the increase of millimeter-wave activity, from the end
of 1991 to the first half of 1993. The radio spectrum of B1313-333 is
extremely flat, ranging from {alpha}_5-90_ = -0.13 in the quiet state
and {alpha}_5-90_ = 0.27 in the active state. We consider B1313-333 a
likely counterpart of 3EG J1314-3431.

Re:PKS B1313-333
There is some confusion as to the redshift of this object in the
literature: Jauncey et al. (1982AJ.....87..763J) measured a redshift
of 1.21 from two lines at {lambda}{lambda}4232, 6166{AA} which they
identified as CIII] {lambda}1909 and MgII {lambda}2798. However, in
their Table 2 the redshift is quoted as 2.21, the erroneous value
picked up by Hewitt & Burbidge (1993, Cat. ) and PKSCAT90.
Veron-Cetty & Veron (1998ESOSR..18....1V) have the correct value
which we list here.

4. 1999A&AS..139..297C
Re:[HB89] 1313-333
1313-333: Large inconsistencies detected in the value assigned to its
magnitude suggest that this source is grossly variable in the optical.

5. 1996ApJ...459..100N
Re:[HB89] 1313-333
J1315-34 = 1313-333.--This is a flat-spectrum QSO.

6. 1994A&AS..105..211S
Re:[KWP81] 1313-333
The redshift is based on two emission lines at lambda = 4232 A and
lambda = 6166 A detected by Jauncey et al. (1982) and identified with C
III] 1909 and Mg II 2798 at z = 1.210, as described in their notes on
individual objects. The incorrect redshift listed in Table II of Jauncey
et al. (1982) is obviously a misprint, which also appears in the
catalogue of Veron-Cetty & Veron (1991).
