Hi everyone:  
I am working on a project that processes the strain data on detectors. In one of the steps, the SNR of GW events is crucial for me to test my method, but sadly only the information about network SNR is found in the GWTC-catalog. I wonder if there’s a website or a file contains the information of **single detector SNR** in this case I don’t have to run matched filtering for every event in each detector.

@BarryG Thank you for your question.

Yes, the SNRs from individual detectors should be in the “candidate data releases” in zenodo.

For example, for GWTC-3, here:

> **[GWTC-3: Compact Binary Coalescences Observed by LIGO and Virgo During the...](https://zenodo.org/records/5546665)**
>
> This material is part of several data products associated with GWTC-3, the third Gravitational-Wave Transient Catalog from the LIGO Scientific Collaboration, the Virgo Collaboration, and the KAGRA Collaboration. For more information, see the paper...

or GWTC-2.1 here:

> **[GWTC-2.1: Deep Extended Catalog of Compact Binary Coalescences Observed by...](https://zenodo.org/records/5759108)**
>
> Data associated with candidates in GWTC-2.1. These are gravitational-wave candidates from the first half of the third observing run (O3a) of the Advanced LIGO and Virgo detectors that pass a false alarm rate threshold of 2/day. We upload a tar...

danke schön!

I think this is exactly what I need, a pipeline result with some triggers!
