Description

We provide a brief description of each folder.  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.  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.

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.
For example, chip_1_q1_theta_JN_0 means a highly precessing equal mass binary with face-on orientation.
Regarding different types of runs:

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.
0noise_fixed_snr30 contains PhenomPv3HM_inj and PhenomPv3_inj.  PhenomPv3HM_inj (PhenomPv3_inj) is the case where IMRPhenomPv3HM (IMRPhenomPv3) waveform model is used.
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.  These files contain the posterior distributions on each of the binary parameters.
We provide the injection parameters inside each directory, inj.pkl.
