These observations demonstrate the existence of binary stellar-mass black hole systems. All uncertainties define 90% credible intervals. In the source frame, the initial black hole masses are 36M and 29M, and the final black hole mass is 62M, with 3.0Mc radiated in gravitational waves. The source lies at a luminosity distance of 410 Mpc corresponding to a redshift z = 0.09. The signal was observed with a matched-filter signal-to-noise ratio of 24 and a false alarm rate estimated to be less than 1 event per 203 000 years, equivalent to a significance greater than 5.1σ.
It matches the waveform predicted by general relativity for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole. The signal sweeps upwards in frequency from 35 to 250 Hz with a peak gravitational-wave strain of 1.0 × 10. On Septemat 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. We show how to embed simulation configuration files and Python analysis code, import simulation data with automatic updating of simulation results, and analyze data and present the results in a Open image in new window file. In this chapter, we illustrate the practice of reproducible research for OMNeT++ simulation based on Pweave and Python. The idea of reproducible research comes as a solution to this problem and suggests that any scientific claims should be published together with relevant experimental data and software code for their analysis so that readers may verify the findings and build upon them in case of computer simulation, the details of simulation implementation and its configurations should be provided as well. As the amount and complexity of model source code, configuration files, and resulting data for simulative experiments are ever increasing, it becomes a real challenge to reliably and efficiently reproduce simulation data and their analysis results published in a scientific paper not only by its readers but also by the authors themselves, which makes the claims and contributions made in the paper questionable.
