The nonspinning binary black hole merger scenario revisited
  We present the results of 14 simulations of nonspinning black hole binaries
with mass ratios $q=m_1/m_2$ in the range $1/100\leq q\leq1$. For each of these
simulations we perform three runs at increasing resolution to assess the finite
difference errors and to extrapolate the results to infinite resolution. For
$q\geq 1/6$, we follow the evolution of the binary typically for the last ten
orbits prior to merger. By fitting the results of these simulations, we
accurately model the peak luminosity, peak waveform frequency and amplitude,
and the recoil of the remnant hole for unequal mass nonspinning binaries. We
verify the accuracy of these new models and compare them to previously existing
empirical formulas. These new fits provide a basis for a hierarchical approach
to produce more accurate remnant formulas in the generic precessing case. They
also provide input to gravitational waveform modeling.
