I tried trending a number of channels back that seemed like they had a large magnitude or interesting abbiration, But when compairing them to live IFO channels they seem to be channels that usually have larger magnitudes.

Even after the Analysis finished there isn't an well defined reason for the lockloss that is obvious to me.
