keyword=slow raster size check and harp scan
We take the 1H05A harp scan and slow raster size check during owl shift.
For the slow raster size, it is about 1.8cm for 1.4V amplitude. picture
can be found in 364541 entry
For harp scan, I took for 5 points(for BPMA position):
-1 -8
-1 -4
-5 -4
+3 -4
-1 -1
for these points, (-1 -8),(-5 -4),(-1 -1) will hit the iron chamber and
cause beam trip in high current, so (-1,-4) is near middle, since the
calibration constant for MCC is not accurate. Toby can get the middle
beam position from raster size check(from raster size and target move).
1H05A harp is pretty better than before, I will try to get the rastersize
from harp data later. harp scan history can be found in 364363 entry.
