Greetings,
Has anybody determined a benchmark for evaluating PMT sensitivity on the
SP-2 platform?  I've recently discovered that our PMT 1 is showing
roughly 30% of the sensitivity of PMT 3 and PMT 2 is showing 65% of the
sensitivity of PMT 3 (at either end of the spectrum).  This is a little
alarming and I would like to determine whether PMT 3 is in fact
performing well or if the sensitivity is down for it as well.  Thanks in
advance for any suggestions.
Cheers,
Karl G.
