addendum, now w/ more data (i.e. whole pp run).... same list as before.

again counting fortran-style starting from the first tofr channel:

tofr ch 5 (suspect tdc path)
tofr ch 14 (suspect adc path)
tofr ch 17 (suspect both paths - fee or mrpc?)

and the tofr channels in the range 30-40 re: this intermittant behavior...

regards...
