I did the harp scan this night, since Trent changed the gain, I took the calibration run for this new gain, also I took for old gain setting. the current I took is 100nA,75nA,50nA. Since MCC failed to raise current to 2uA pulser, I took the harp scan in 2uA pulser . the signal is noise , you can see the snapshot in: http://hallaweb.jlab.org/halog/log/html/1204_archive/120411034348.html
