* Event list is updated following the SNR criteria (inspiral SNR>6). See [this script](https://git.ligo.org/publications/O3/o3a-cbc-tgr/-/blob/master/notebooks/Event_Selection_Optimal_SNR.ipynb) for details of the SNR calculation. The inspiral cut-off is chosen from the relation ``` tig_freq = 0.018 / mtotal_s ```. Notice that our event list is the same as that of [TIGER pre-merger](https://git.ligo.org/publications/O3/o3a-cbc-tgr/-/wikis/EventSelection#tiger-premerger) events.
