Data

Data need to be downloaded from the github release page. The total size is ~35GB. To download the entire dataset use our download_all.py script.

We provide two types of data products, named *_result.json and *_chipav.dat.

• The result.json files are the raw bilby outputs, see here for instructions. Each of these files contains a nested set of dictionaries with all the information of the injection (true values, waveform arguments, priors, posteriors, log evidence etc...).
• The chipav.dat files contain the posterior samples of the averaged .$\chi_p$ estimator. Samples for the heuristic definition of $\chi_{p}$ are provided by default and can be found in result.json.

Readme

The data provided refer to the results of the paper as follows:

• Data to reproduce Fig. 2 and Fig. 3 of the paper are listed as DL_XXXX where DL stands for luminosity distance and XXXX refers to the value in Mpc.

• The 100 injections used in Fig. 4 and Fig. 5 are listed as uni_XX where XX ranges from 00 to 99. Injections are sorted in in ascendig order of $\chi_{p}$. The prefix uni stands for uniform because of our targeted $\chi_{p}$ distribution. For all these runs, injection and recovery are done with the IMRPhenomXPHM waveform models using the standard uninformative priors (see the paper).

• In Fig.6, the red posteriors correspond to the injections labeled uni_XX from above with XX=[25,98]. The green posteriors are performed using volumetric priors and can be reproduced using files starting with prior_XX. The yellow posteriors are done at higher SNR value and are provided as prior_XX_SNR_YY.

• In Fig. 7, the posteriors obtained injecting and recovering with IMRPhenomXPHM are the ones are those labeled uni_XX with XX=[21,81]. The other runs obtained with different combination of IMRPhenomXPHM, IMRPhenomTPHM and NRSur7dq4 (shortened respectively as XP, TP and NR) can be reproduced using files named syst_XX_WINJ_WREC where WINJ and WREC indicate the waveform model used in injection and recovery, respectively.
