10 note(s) found in NED.

1. 2008ApJ...687..767K
Re:PG 1202+281
(Fig. 34).-This source has a number of nearby galaxies, the brightest and
nearest of which we fit simultaneously. The primary host is well described by a
single-component bulge (n = 4).

Re:PG 1202+281
PG 1202+281: Archival HST UV data in the wavelength range 2400-3277 A are also
used to increase the S/N. The flux density of this spectrum agrees very well
with the new HST spectrum, although this object is highly variable (Sitko et al.
1993 and references therein).

Re:GQ Com
q1202+2810, z = 0.165.-GQ Comae. This is the well known variable
quasar. The FOS spectra are presented by J98. G270(2), G190(2), G130.

Re:PG 1202+281
BLW give EW(C IV) = 0.4A. This is based on the C IV line-peak asymmetry.
However, inspection of the H{beta} profile in BG92 reveals the same
asymmetry. Since H{beta} absorption is extremely rare, we conclude that
the emission-line asymmetry is most likely not due to absorption and
adopt here EW(C IV) = 0A. A rather high S/N ROSAT spectrum does not
reveal any evidence for absorption (L97)

Re:PG 1202+281
PG 1202+281 = GQ Comae. - We were unable to observe this QSO because of
the sensitivity limitations of our fast tip-tilt guider. However,
Bahcall et al. (1997) have observed this system with HST/WFPC2 and find
that the host galaxy appears to be a small elliptical E1 galaxy.

6. 2000ApJS..129..563S
Re:PG 1202+281
1202+281 (z_em_ = 0.165). - The modest average velocity equivalent
width for Mg II of = 114 km s^-1^ is consistent with the
21 cm emission full extension width of {DELTA}v(H I) = 119 km s^-1^
(from Table 2) and the absence of H I HVCs along this line of sight.

7. 1998ApJ...495..152L
Re:PG 1202+281
PG 1202+281.--BKS95 find two companions. There is a bright companion that can
be clearly seen on the McLeod & Rieke H-band image. We found no studies of its
broader environment.

8. 1997ApJ...479..642B
Re:PG 1202+281
The host of this radio-quiet quasar, also known as GQ Com, is a small
elliptical E1 galaxy. Stockton & MacKenty (1987) showed that the compact
galaxy ~5" from the quasar, PA = 71^deg^, is at the same redshift as the
quasar. Boroson et al. (1985) reported that the off-nuclear spectra are
dominated by a red continuum, with [O III] lines and possibly H{alpha} in
emission, and a possible Mg I b absorption feature. The V magnitude
estimated from the McLeod & Rieke (1994b) H-band images is in good
agreement with the magnitude determined by our two-dimensional model.

9. 1996ApJS..104...37M
Re:PG 1202+281
PG 1202+281.--This radio-quiet quasar has a very large EW(C IV
{lambda}1549_BC_) because of an extremely weak UV continuum (not an artifact
of the FOS reduction procedure).

10. 1996AJ....111..645F
Re:[HB89] 1202+281
confused object to west, no nebulosity on source, but many faint
objects nearby; confusion is much less noticable on POSS-O.
