  10. 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. K_ecal=2.5 K_ecal=1.5 K_ecal=1.75

  11. Ecal calibration constant K_ecal=2.5 K_ecal=1.5 K_ecal=1.75

  12. Nu_e electron energy (k_ecal=2.5)

  13. Nu_e electron energy (k_ecal=2.5) • When electron track is reconstructed.

  14. Nu_e electron energy (k_ecal=1.5)

  15. Fake ADC -- Scan Time • 10000 adc hit for 120 sec (rate=~83 adc/s) • This is the rate in manual taken data. • Nominal pedestal position=371 • Nominal pedestal sigma=10 • nADC = rate*scanTime • Fill Gaus(371+Shift,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
