Abstract:
We examine the parameter accuracy that can be achieved by advanced
ground-based detectors for binary inspiralling black holes and neutron stars.
We use the 2.5 PN spinning waveforms of Arun et al. (2009). Our main result is
that the errors are noticeably different from existing 2PN studies for aligned
spins. While the masses can be determined more accurately, the individual spins
are measured less accurately compared to previous work at lower PN order. We
also examine several regions of parameter space relevant to expected sources
and the impact of simple priors. A combination of the spins is measurable to
higher accuracy and we examine what this can tell us about spinning systems.
