1. 2005MNRAS.358..481K
Re:ESO 157- G 018
ESO 157-G18. The approaching side of this dwarf system shows anomalous
kinematics, both for the stars and the gas (see Paper III). This side was
therefore not included in the fit. As in ESO 142-G24, the rotation curve rises
slowly such that C M/L parameter is rather large in fitted range. The inferred
intrinsic velocity dispersion is the lowest in the sample.

Re:ESO 157- G 018
ESO 157-G18. This dwarf system is lopsided, both in terms of its H I
kinematics and density distribution. This is directly apparent from the
global profile, which is single peaked, and the XV map, which reflects a
slowly rising/flat rotation curve at the approaching/receding side. No H
I is detected at radii beyond the stellar disc.The lopsidedness may be
related to the presence of the small companion APMBGC 157 + 052 + 052
(Section 3.4), or the proximity of the S0 liner NGC 1553 and/or the
elliptical NGC 1549.

Re:ESO 157- G 018
ESO 157-G18. APMBGC 157+052+052 is located at a projected distance of
110 arcsec or approximately three disc scalelengths. Its apparent
magnitude in I-band was determined using the photometry of de Grijs
(1998) to be m_I_ = 14.87 mag. At the adopted distance of the main
galaxy this translates to a luminosity L_I_ = 1.210^8^ L_sun_ (using
M_sun_,_I_ = 4.11), or approximately 10 per cent of the I-band
luminosity of ESO 157-G18. An interesting feature is an offset of ~7
arcsec (one-third of the FWHM of the synthesized beam) between the H I
and the optical centres of this companion. It is conceivable that this
offset has resulted from an ongoing interaction with ESO 157-G18.

4. 2004MNRAS.351.1247K
Re:ESO 157- G 018
ESO 157-G18. On the approaching side, the stellar velocity and velocity
dispersion are larger. The asymmetry in the velocities is also seen in
the H I and the [O III] emission lines (see Paper III).

5. 2000MNRAS.313..800D
Re:ESO 157- G 018
Despite its regular appearance, ESO 157-G18 is clearly dusty and shows
irregularly located regions of high extinction throughout its disc,
which may be the cause of the small vertical colour gradient, indicating
redder colours with increasing z height (Fig. 2b; T = 6.0).
