 Here is the optics plan for 2.254GeV with 5T and 0 deg target field.
 Before doing optics, beam center and slow raster size have to be determined.
 
 No LHe, LHRS starts at 0% and right HRS start at 4%:
 
 1. Delta scan:  C12, sieve in , no raster  (3 hours)
 Left HRS: -4%, -3%, -2%, -1%, 0%, 1%, 2%, 3%, 4%
 Right HRS: 4% (Right septum I<=920A, so can only go to 4%.)
(-4%, -1% and +3% can be ignored if running out of time) 
 NOTE: if possible, do 3% for right arm, which is 930A.
 
  
 **Ramp left dipoles back to 0% when finish. (40 minutes)
 
 2. Beam position scan: C12, delta=0; sieve in, slow raster only,  (40
minutes)
 Config the slow raster to jump in the following way:
 1)between (x=-5, y=-5) and (5,5)
 2)between x=0, y=+/-5
 3)between x=+/-5, y=0
 
 
 3. Acceptance calibration, part 1:  C12, sieve in, delta=0  (10 minutes)
 1) both rasters on
 
 4. Pointing: CH2, sieve in ,delta=0, no rasters (30 minutes)
 Take data till the H peak of a normal sieve hole can be fit.
 
 **Escorted access to move sieve out when finish (30 minutes)
 5. Acceptance calibration, part2:  C12, sieve out, delta=0 (20 minutes)
 1) no rasters
 2) both rasters
 
 
 Estimated time: 7 hours
 
 At the end of the optics, refill LHe, change to the 1st production point,
 start dilution runs then polarize NH3 target.
