"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>",
