    Two mistakes:
    
    1) the terminal is maintained by RHIC, not ITD. If it breaks, call
       the MCR and they will send somebody to look at it.
    
    2) cycling the power on the *monitor* has no effect on the terminal.
       Most likely it hung and cycling the power on the *terminal*
       would have had fixed it.

    - yes, please include fb1 and fb3 in all runs (not just pedestals).
      both are fully operational and I would like to excercise them.

    - pedestal runs should be taken *at running conditions*, i.e. with
      all regular high voltages turned on. This is because the pedestals
      program measures the noise levels in the TPCs. The noise
      levels are lower than nromal when high voltages are off so
      the pedestals program will measure thew wrong numbers, unsuitable
      for data taking.
