 +1) scan pedestals as a function of gain and shutter. Time base set to 20mus
 +
 +2) align magnet with flange
 +
 +3) correlate  time stamps : spectr=19:10:30 --> monitoring=18:10:20
 +
 +4) estimate rough calibration constants @ gain =900, shutter= 4 (x20mus) {1,1.4,0.7,1.3,0.5}
 +
 +With B=0 nice collimated beam!

 +TODO: 
 +  A) redo ROI for camera 1,2
 +  B) GUI:
 +      - debug spectrum plot
 +      - add possibility to subtract flat component 
 +      - correct for dead fibers
 +      - rebin (4 or 8)
 +  C) estimate effect of lanex by removing it
 +  D) screen spectrometer from direct laser
 +  E) intercalibrate cameras offline (with electroluminescence)
 +  F) integrate instructions for the camera readout into the manual

 +New ROI file done  (files calib2012Oct12).
 +Run 101 pedestal run
 +Run 102 and run 103 (skip first 100/200 events) runs done moving a lamp over the fibres to check mapping and intercalibration  (0.8, 1.5, 1, 1.3, 1)
 +
 +TO DO: redo wrapping of fibres especially those corresponding to maroc 0 and 4!

 +Shifted camera by 5mm

 +Rewrap fibers with thick aluminum
