Rare very-large-time FLSHits
About 1 out of every 10k FLSHits in a cosmic file I'm looking at (assumed representative) has a time of order 1e11 or 1e12 ns. My guess is that in certain cases, the Monte Carlo (g4nova?) is double-correcting from seconds to nanoseconds. This is a minor problem unless it is indicative of a deeper hidden problem. In the file I've been using, these bad hits are always induced by an electron (according to FLSHit::fPDG).
Someone familiar with g4nova might try to track this down at least to confirm that something isn't horribly broken.
