BCM Linearity calibration  Tuesday, Feb. 20  (0800--1230)
---------------------------------------------------------
The 60min BCM Linearity calibration seems to have had some problems getting
going.  AFAICT, the good data started at 11:29; stopped at 12:03.
  Halog entry (FWIW: screen snaps are good, but render incorrectly in firefox 2.0.0)
    http://www.jlab.org/~adaq/halog/html/0702_archive/070220120532.html
  Data /usr/opdata/bcm_hallA/BcmLog_127
  CODA runs: 6631/26617
The calibration was done from 68 uA down to 0.2 uA  (even higher starting
point than requested).  See OPS Log entry

New runs.  Arne is working on the analysis
-------------------------------------------------------------
--- Sunday, Feb 18
-  Nominal requested current:     0.2 uA
-  CODA runs:    6559/26543.
-  BCM log file: BcmLog_119
NOTE: MCC called us halfway through the run to start the logging
      so the files are not complete.

-  Nominal requested current:     1.0 uA
-  CODA runs:    6567/26551
-  BCM log file: BcmLog_121
NOTE: Should be OK.  (I don't know what happened to BcmLog_120 though...)

--- Monday, Feb 19
-  Nominal requested current:     0.5 uA
-  CODA runs:    6609/26595
-  BCM log file: BcmLog_122
NOTE: Beam trip for ~2 minutes during calorimeter run.

-  Nominal requested current:     0.7 uA
-  CODA runs:    6612/26598
-  BCM log file: BcmLog_123
NOTE: MCC reported problem with Calorimeter script.  Probably junk?

--- Tuesday, Feb 20
-  Nominal requested current:     5.0 uA
-  CODA runs:    6626 / 26612
                 6627 / 26613  (5.0uA data at start, some 0.2 uA data at the end)
-  BCM log file: BcmLog_124
NOTE: Left arm CODA run stopped during the Calorimeter run due to an event
      limit.  Shift crew started a second pair after ~1min pause.  Calorimeter
      run is good.

-  Nominal requested current:     0.2 uA
-  CODA runs:    6627 / 26613
-  BCM log file: BcmLog_124
NOTE: A 0.2uA run was done right after the above 5.0 uA run without stopping
      CODA runs or BCM logging (hence same files).
