High Flagging Statistics with Aoflagger for uGMRT Data

[phetogoportia]

I am using Aoflagger to flag data from the uGMRT; the flagging statistics appear unusually high. I would like to know if these statistics are reasonable.

Hi @phetogoportia,

You can try inspecting the spectra of the data before flagging to get an idea of how much of the data is expected to be flagged and what is actually flagged after running AOflgger.
Alternatively, please try a different flagging strategy or adjust it appropriately.

Regards
