  This paper presents a parameter estimation analysis of the seven binary black
hole mergers---GW170104, GW170608, GW170729, GW170809, GW170814, GW170818, and
GW170823---detected during the second observing run of the Advanced LIGO and
Virgo observatories using the gravitational-wave open data. We describe the
methodology for parameter estimation of compact binaries using
gravitational-wave data, and we present the posterior distributions of the
inferred astrophysical parameters. We release our samples of the posterior
probability density function with tutorials on using and replicating our
results presented in this paper.
