Revisiting the ringdown of GW150914
<p>Data release for our publication on "Revisiting the ringdown of GW150914." Released files include posterior samples for all ringdown parameter estimation runs used in the paper. We also include a Jupyter notebook that reproduces plots in the paper from these data (<em>paper_plots.ipynb</em>), as well as a Jupyter notebook that replicates an individual ringdown analysis like those that produced the enclosed parameter estimation results (<em>GW150914_sample_analysis.ipynb</em>).</p> <p>Code associated with this release is also made available through GitHub <a href="https://github.com/maxisi/gw150914-ringdown">here</a>.</p>
Posterior samples for "Searching for a Ringdown Overtone in GW150914"
<p>Posterior files associated with <em>Searching for a Ringdown Overtone in GW150914 </em>(<a href="https://arxiv.org/abs/2205.07809">arXiv:2205.07809</a>, <a href="https://journals.aps.org/prd/abstract/10.1103/PhysRevD.106.043005">Phys. Rev. D 106, 043005</a>).</p> <p>We provide samples for both the GW150914 analysis (<code>posterior_samples/GW150914</code>) and the injection campaign (<code>posterior_samples/injection_campaign</code>). For the GW150914 analysis, where multiple models were used, the folder naming follows the convention:</p> <p><code>{number of wavelets included in the model}W{QNM content described by lmn indices}</code></p> <p>with the kerr-deviation analysis having the additional label <code>_with_deviation</code>.</p> <p>Only the <code>3W220221</code> model was used in the injection campaign. There, subfolders are named according to the injection time in seconds (where <code>m</code> indicates a minus value, relative to t_ref as detailed in the paper). The exception is the noiseless injection, which is in the <code>noiseless</code> folder.</p> <p>Each directory contains a <code>posterior_samples.dat</code> file and a <code>sampler_output.json</code> file which contains the log-evidence (natural log) and the estimated error on the log-evidence.</p> <p>Notebooks to reproduce the figures in the paper are available in the <code>plots</code> folder.<br> </p>
Posterior samples for "Frequency-Domain Analysis of Black-Hole Ringdowns"
<p>Posterior files associated with <em>Frequency-Domain Analysis of Black-Hole Ringdowns</em> (<a href="http://arxiv.org/abs/2108.09344">arxiv:2108.09344</a>, <a href="https://journals.aps.org/prd/abstract/10.1103/PhysRevD.104.123034">Phys. Rev. D <strong>104</strong>, 123034</a>).</p> <p>Folder naming:</p> <ul> <li>{event name} <ul> <li>SNR{injection signal-to-noise ratio} <ul> <li>frequency_domain <ul> <li>{number of wavelets included in the model}W{QNM content described by lmn indices} <ul> <li>{ringdown start time in ms}_{ringdown start time prior width in ms}</li> </ul> </li> </ul> </li> <li>time_domain <ul> <li>{QNM content described by lmn indices} <ul> <li>{ringdown start time in ms}_{ringdown start time prior width in ms}</li> </ul> </li> </ul> </li> </ul> </li> </ul> </li> </ul> <p> </p> <p>For example, the file </p> <p>GW190521/SNR15/frequency_domain/1W220/12-7_01/posterior_samples.dat</p> <p>contains the results of a frequency-domain analysis of the GW190521-like injection (at signal-to-noise ratio 15) using <span class="math-tex">\(W=1\)</span> wavelet with just the fundamental <span class="math-tex">\(\ell = m = 2\)</span>, <span class="math-tex">\(n=0\)</span> QNM. It has a Gaussian prior on the ringdown start time centered 12.7 ms after the time of peak strain, with a width of 1 ms.</p> <p>The special-case two-interferometer analysis with Virgo excluded has "_HL" appended to its folder name.</p> <p>Each directory contains a 'posterior_samples.dat' file (see the 'plot_example.ipynb' for more information on reading the posterior files) and a 'sampler_output.json' which contains the log-evidence and the estimated error on the log-evidence.</p>
Supporting information for "Kinetics of CN(v=1) reactions with butadiene isomers at low temperature by cw-Cavity Ringdown in a pulsed Laval flow with theoretical modelling of rates and entrance channel branching
<p>This file contains the master equation inputs for all the reactions studied, as well as all the details on stationary points and VRC-TST fluxes necessary to reproduce the simulations. </p>
