Ecal calibration constant

• Old study showed Ecal calibration constant 2.5 is
  better than 1.5
• Mean of (recoE-trueE)/trueE become constant for
  theta, Vz depedence
• Value 1.5 is from dE/dx weighting.

Fake ADC -- Scan Time

• 10000 adc hit for 120 sec (rate83 adc/s)
• This is the rate in manual taken data.
• Nominal pedestal position371
• Nominal pedestal sigma10
• nADC ratescanTime
• Fill Gaus(371Shift,sigma) nADC times.
• Two pedestal histogram (PedA, PedB) are made with
  Gaus(371,sigma)
• No photoelectron ADC, just pedestal
• No systematic error
• No strip-to-strip variation
• No electronics channel-to-channel variation
