Many of these relate to the modeling, detection and characterization of signals from binary inspirals with an extreme component-mass ratio of $\\lesssim10^{-4}$. In this paper, we draw attention to the issue of systematic error in parameter estimation due to the use of fast but approximate waveform models; this is found to be relevant for extreme-mass-ratio inspirals even in the case of waveforms with $\\gtrsim90\\%$ overlap acc","authors_text":"Alvin J.
