hi - the tdc dists look o.k. with the small statistics i'm looking
at... also, the entries i see >1000 are accompanied by ADC hits (i.e.
they're shaded red in my usual histograms) so presently i'm thinking
this isn;'t a problem and it's the latter of your two cases...
but i'll take another look at this with the next big slug of localmon data
- thanks for mentioning it...
