Characteristic Hyperparameter Values for Power Law + Dip + Break Model in GWTC-3

Document #:

LIGO-T2100512-v8

Document type:

T - Technical notes

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.
