04:00am ~ 10:30 am,12:30 ~ 15:00  DeltaP Optics Scan by Min:
  Fast Raster was on for the -4%, -3% -2% and -1% runs. But it was OK
since the size of raster is small and dP is not very strong correlated
with angle. The complete dP scan was finished at about 14:55pm.

10:30am ~ 12:30pm BCM calibration by Alexandre,
   Found BCM readout problems. Did not complete. Chad reported that
software work can not fix the problem. Alex tried to control the Harp
motion but couldn't. Request Control access to locate their IOCs and
rebooting them did not fix the readout. Tony Dela Cruz is going to
diagonize the issue tomorrow morning. 

15:30pm   Control Access:
  a) Locating SuperHarp IOCs
  b) Checking BCM connection by John Musson and Alex.
      Found some conflict bettween old BCM modules and new BCM modules.
Need to work out solution before the production runs.
  c) Strong Brook group install gas bottle.

17:00pm ~ 12:00a?  BCM calibration
    Still taking data. Set the momentum at Elastic, and take data at
current 1uA, 100uA, 50uA w/wo fast raster.
