keyword=scaler strip chart, Qasy, etc
A strip chart of scaler quantities was made, see fig 1.
To use this, login to adaql4 as adaq, then "cd ~adaq/dvcs/scaler"
and then "root .x qasy_strip.C" (without the quotes). More
details are in the README file. In the plot the following
are plotted (starting from top left, CCW): 1) BCM U3 (upstream x3),
2) trigger T5 (main DVCS trig), 3) Charge asymmetry on BCM U10,
and 4) Chg asy on BCM U3.
When the beam is off, there is no update on charge asymmetry (the
middle portion of the plot). X axis is in seconds, the plot is
updated every 30 sec, and one can see the chg asy is small, generally
less than 0.001 in absolute value.
