keyword=slit was out
The "-1" meant the slit was totally retracted, hence the very hight
compton rate. They should not have been retracted. The slit might still
be increased later, to compensate low QE as well as low laser power to
deliver the current we want, if the QE and lase power continue to drop.
MCC will check them during Tuesday (Dec. 16) morning's RF recovery .
