Hello,

Is there a means in which to query a list of just all confirmed BBH merger events up to 04b (GWTC5) that have been publicly released?

Hello,

This depends on what format you want to have your list on.

You can get a list of all GWTC events through the [event portal](https://gwosc.org/eventapi/html/GWTC/).

If you want query the list in a python script, you can scan the api, for example this link has all the GWTC events with parameters:

[https://gwosc.org/api/v2/catalogs/GWTC/events?include-default-parameters](https://gwosc.org/api/v2/catalogs/GWTC/events?include-default-parameters)

I would suggest using the [python client](https://gwosc.readthedocs.io) to go through the result pages and filter each event by mass.

```auto
from gwosc.api import v2 as apiv2

url = "https://gwosc.org/api/v2/catalogs/GWTC/events?include-default-parameters"
events = apiv2.produce_fetched_objects(url)

for event in events:
    # filter here
    ...

```

I hope that helps
