Hi Jacopo Thanks for the review! I think most of this relates again to the way we specify the different AGC configs in the tuning file, and how we refer to the correct ones. As per my reply to the previous patch, I think I will try a slightly different scheme where we index the AGC configs with a name ("normal", "short" or "long"). This is very similar to the way we handle this elsewhere (e.g. AGC exposure modes and so on). So it's probably not worth replying again here, instead let me post a revised version and then we can revisit all this then!
