Validating the Effective-One-Body Numerical-Relativity Waveform Models
  for Spin-aligned Binary Black Holes along Eccentric Orbits
  Effective-one-body (EOB) numerical-relativity (NR) waveform models for
spin-aligned binary black holes (BBHs), known as the SEOBNR waveform models,
are based on the EOB theoretical framework and NR simulations. SEOBNR models
have played an important role in the LIGO scientific collaboration (LSC)
gravitational wave (GW) data analysis for both signal search and parameter
estimation. SEOBNR models for quasi-circular orbits have evolved through
version 1 to version 4 by extending their validity domain and including more NR
results. Along another direction, we recently extended SEOBNRv1 model to
SEOBNRE model which is valid for spin-aligned BBH coalescence along eccentric
orbits. In this paper we validate this theoretical waveform model by comparing
them against the numerical relativity simulation bank, Simulating eXtreme
Spacetimes (SXS) catalog. In total, 278 NR waveforms are investigated which
include binaries with large eccentricity; large spin and large mass ratio. Our
SEOBNRE can model the NR waveforms quite well. The fitting factor for most of
the 278 waveforms is larger than 99\%. It indicates that the SEOBNRE model
could be used as template waveforms for eccentric spin-aligned BBH coalescence.
