  "abstract": "<p>Welcome to the data release of our recent paper titled &quot;The interplay of spin-precession and higher harmonics in the parameter estimation of binary black holes&quot;.<br>\nWe provide all the posterior samples used to make different figures/conclusions that went into the <a href=\"https://arxiv.org/abs/2110.00766\">paper</a>.&nbsp;<br>\nFor any clarifications regarding the data structure please write to us at krnava@aei.mpg.de or at frank.ohme@ligo.org<br>\nThank you!</p>\n\n<p><strong>Description</strong></p>\n\n<p>We provide a brief description of each folder. &nbsp;As we discuss in detail in the papers, we study the measurability of spin-induced orbital precession in generic binary systems, employing two waveform models IMRPhenomPv3HM and IMRPhenomPv3. The parameters are estimated using the gravitational-wave data analysis toolkit parallel Bilby. &nbsp;Our injections are assuming the binary produced fixed signal-to-noise ratio in the three detector network consisting of two LIGO and one Virgo detector at their design sensitivities.</p>\n\n<ul>\n\t<li>General convention followed for directory naming: `chi_1` highly precessing system and `chi_2` slowly precessing system. `q1`, `q3` and `q7` correspond to three different mass ratios considered (maps to inverse mass ratios, 1/q=1, 3, 7) at a fixed total mass 40Msun. Finally, `theta_JN_0` represents a face-on system and `theta_JN_piby2` represents an edge-on binary.</li>\n\t<li>For example, `chip_1_q1_theta_JN_0` means a highly precessing equal mass binary with face-on orientation.</li>\n\t<li>Regarding different types of runs:\n\t<ul>\n\t\t<li>&nbsp;&nbsp;`0noise_fixed_snr30` contains injections at a fixed signal-to-noise ratio of 30 and `0noise_fixed_snr30` contains injections at a fixed signal-to-noise ratio of 60.</li>\n\t\t<li>&nbsp;`0noise_fixed_snr30` contains `PhenomPv3HM_inj` and `PhenomPv3_inj`. &nbsp;`PhenomPv3HM_inj` (`PhenomPv3_inj`) is the case where IMRPhenomPv3HM (IMRPhenomPv3) waveform model is used.&nbsp;&nbsp;</li>\n\t\t<li>Data files, `PhenomPv3HM_pesummary.dat` means IMRPhenomPv3HM is employed as the recovery model and `PhenomPv3_pesummary.dat ` means IMRPhenomPv3 is employed as the recovery model. &nbsp;These files contain the posterior distributions on each of the binary parameters.</li>\n\t\t<li>We provide the injection parameters inside each directory, `inj.pkl`.&nbsp;</li>\n\t</ul>\n\t</li>\n</ul>",
