gwastro/o2-bbh-pe: v2.2 data release of O2 Binary Black Hole posterior samples

This is the v2.2 data release associated with the parameter estimation analysis of the binary black-hole signals from Advanced LIGO-Virgo's second observing run, using the PyCBC Inference toolkit : https://iopscience.iop.org/article/10.1088/1538-3873/aaef0b . A companion paper presenting our parameter estimation analysis and the data release is available here : https://arxiv.org/pdf/1811.09232.pdf.

The analysis was performed using the PyCBC v1.12.3 code on the gravitational-wave data available at https://www.gw-openscience.org/catalog/GWTC-1-confident/html/ . Descriptions of the gravitational-wave data can be found in the paper https://arxiv.org/abs/1811.12907 .

The changes in this release are

• An update to the plotting code in data_release_o2_bbh_pe.ipynb for generating Figs. 1, 2, and 3 in the companion paper to take into account cases where a boundary bias may be introduced for plotting probability contours.
• Addition of a plotting code in data_release_o2_bbh_pe.ipynb that generates a corner plot showing estimates (median and 90% credible interval) and posterior distributions for all the parameters presented in Table 1 of the companion paper.
• Addition of a notebook o2_bbh_pe_skymaps.ipynb that demonstrates the method for visualizing sky location posteriors as presented in Fig. 4 of the manuscript.

The data and configuration files included remain the same as in the v2.1 release.

This release includes :

• posterior and prior samples from parameter estimation analyses of the seven binary black-hole events---GW170104, GW170608, GW170729, GW170809, GW170814, GW170818, and GW170823.
• PSDs used in each of the analyses
• configuration files and run scripts for running the analyses and generating the data.
• tutorials for manipulating the data and reconstructing the figures in the companion paper.
