NGC 3311: the HST imaging was published by Laine et al. (2003). No clear
rotation or velocity substructure can be seen in the radial kinematic profiles,
but the velocity dispersion profile has a positive gradient.
Abell 1060 (NGC 3311). - The central galaxy in the Hydra cluster was
one of four galaxies presented here that were observed by D. Geisler,
J. Elias, and E. Ajhar as part of NICMOS program 7820. The images were
reduced for SBF analysis using the software and procedures described in
this paper. NGC 3311 has some dust in the central region that was masked;
the SBF fit in the outer regions is nearly perfect and the S/N ratio is
The dust cloud has an elongated structure oriented along the NS
direction while the ionized gas cloud is roughly spherical, with a weak
absorption feature which coincides with the dust pattern.
Overexposed center, very faint(r?): 0.65 x 0.5. Pretty bright lens,
extremely faint corona. Possible E+1.
