Abstract
This article provides supplemental information for a Letter reporting the rate of (BBH) coalescences inferred from 16
days of coincident Advanced LIGO observations surrounding the transient (GW) signal GW150914. In that work we
reported various rate estimates whose 90% confidence intervals fell in the range 2–600Gpc−3yr−1. Here we give
details on our method and computations, including information about our search pipelines, a derivation of our
likelihood function for the analysis, a description of the astrophysical search trigger distribution expected from
merging BBHs, details on our computational methods, a description of the effects and our model for calibration
uncertainty, and an analytic method for estimating our detector sensitivity, which is calibrated to our measurements.
