Summary of the CDF top mass measurements and their combination as of March
2009. We combine published results from Run-I (1992-1996) with the most recent
preliminary and published Run-II (2001-present) measurements using up to
3.2 fb-1 of data. Taking correlated uncertainties properly into account
the resulting preliminary CDF average mass of the top quark is
Mtop = 172.6 ± 0.9 (stat) ± 1.2 (syst) GeV/c2
which corresponds to a total uncertainty of 1.5 GeV/c2, or equivalently to a 0.85% precision.
More information can be found in CDF Note 9714.
