A new tool exists to check scalers.  On adaq account on
SunOS type "rscaler 1421 1424" to get a printout like below.

To judge if there are trigger problems, some hints:  1) only
compare same physical conditions; 2) take a look at the run
time and statistical significance; 3) look at ratio of trigger
rate to beam current.

Note, a negative beam current is due to the X10 V-to-F counting
beyond 32-bits, which I think happens in roughly 1 hour at high
currents.  Not a disaster.  We update scalers in the CODA file
once per 2 sec, presumably one sees the X10 ramping up.

Source is /home/adaq/scaler/rscaler/rscaler.c.  If you compile, 
put exec into /home/adaq/bin/SunOS.  You might have to type "rehash"
the first time you use this.

Runs that dont end normally (CODA crash) dont show up in list.
