Abstract (from CDS):

We present (g475- z850) color and z850-band surface brightness fluctuations (SBFs) measurements for 43 early-type galaxies in the Fornax cluster imaged with the Hubble Space Telescope Advanced Camera for Surveys. These are combined with our earlier measurements for Virgo cluster galaxies to derive a revised, nonlinear calibration of the z850-band SBF absolute magnitude as a function of (g475- z850) color, valid for the AB color range 0.8 < (g475- z850) < 1.6. In all, we tabulate recalibrated SBF distances for 134 galaxies in Virgo, Fornax, the Virgo W' group, and NGC 4697 in the Virgo Southern Extension. The calibration procedure yields a highly precise relative distance modulus for Fornax with respect to Virgo of Δ(m - M)FV= 0.42±0.03 mag, or a distance ratio dF/dV = 1.214±0.017. The resulting Fornax distance modulus is (m - M)For= 31.51±0.03±0.15 mag, corresponding to dF= 20.0±0.3±1.4 Mpc, where the second set of error bars reflects the total systematic uncertainty from our assumed Virgo distance of 16.5 Mpc. The rms distance scatter for the early-type Fornax cluster galaxies is σd= 0.49+0.11–0.15 Mpc, or a total line-of-sight depth of 2.0+0.4–0.6Mpc, consistent with its compact appearance on the sky. This translates to a depth scatter smaller than the intrinsic, or "cosmic," scatter σcos in the SBF calibration, unlike the case for the larger Virgo cluster. As a result, we are able to place the first tight constraints on the value of σcos. We find σcos = 0.06±0.01 mag, with a firm upper limit of σcos< 0.08 mag, for the subsample of galaxies with (g475- z850)>1.02, but it is about twice as large for bluer galaxies. We also present an alternative SBF calibration based on the "fluctuation count" parameter, a proxy for galaxy mass. This gives a consistent relative distance but with larger intrinsic scatter, and we adopt the result from the calibration on (g475- z850) because of its basis in stellar population properties alone. Finally, we find no evidence for systematic trends of the galaxy distances with position or velocity (e.g., no current infall); the Fornax cluster appears both compact and well virialized.
