Abstract:
This document contains the maximum posterior draw of the two Power Law + Dip + Break models highlighted in https://dcc.ligo.org/LIGO-P2100239/public
(described in detail in https://dcc.ligo.org/LIGO-P2100403/public), when fit to events in GWTC-3 with a FAR 1/4 per year.

There are 7 files in this document:
* README.html contains some examples and minimal instructions on how to use the other files
---------
* O1O2O3all_mass_g_iid_mag_iid_tilt_powerlaw_redshift_maxP_sample.json is a json file with the value of each hyperparameter at the maximum-hyperposterior draw for the independent pairing model
* O1O2O3all_mass_g_iid_mag_iid_tilt_powerlaw_redshift_mass_maxP_pdf.h5 is an hdf5 file with the model evaluated at this draw.
---------
* O1O2O3all_mass_h_iid_mag_iid_tilt_powerlaw_redshift_maxP_sample.json is a json file with the value of each hyperparameter at the maximum-hyperposterior draw for the power law pairing model
* O1O2O3all_mass_h_iid_mag_iid_tilt_powerlaw_redshift_mass_maxP_pdf.h5 is an hdf5 file with the model evaluated at this draw.
* O1O2O3all_mass_h_iid_mag_iid_tilt_powerlaw_redshift_maxP_events.h5 is an hdf5 file with 10^6 samples drawn from this model

Notes and Changes:
New "events" file to reflect addition of a Jacobian factor (see this commit: https://git.ligo.org/amanda.farah/gwpopulation_pipe/-/commit/4f853ac46db196022127769a01ff9aa4d20ea607)
