Posterior samples for "Frequency-Domain Analysis of Black-Hole Ringdowns"

Posterior files associated with Frequency-Domain Analysis of Black-Hole Ringdowns (arxiv:2108.09344, Phys. Rev. D 104, 123034).

Folder naming:

• {event name}
  • SNR{injection signal-to-noise ratio}
    • frequency_domain
      • {number of wavelets included in the model}W{QNM content described by lmn indices}
        • {ringdown start time in ms}_{ringdown start time prior width in ms}
    • time_domain
      • {QNM content described by lmn indices}
        • {ringdown start time in ms}_{ringdown start time prior width in ms}

For example, the file 

GW190521/SNR15/frequency_domain/1W220/12-7_01/posterior_samples.dat

contains the results of a frequency-domain analysis of the GW190521-like injection (at signal-to-noise ratio 15) using \(W=1\) wavelet with just the fundamental \(\ell = m = 2\), \(n=0\) 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.

The special-case two-interferometer analysis with Virgo excluded has "_HL" appended to its folder name.

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.
