PandoraPFA Calibration

I had a go at the Pandora calibration, it's well documented and seems straight forward enough. I've put a script for a Grid job in the subversion repository to create all the samples necessary so it can be repeated if the detector changes (https://svn.phy.bris.ac.uk/svn/ilc_z_higgs/MarksStuff/PandoraCalibrationEventGeneration).
The files I generated for LDC00SC are in "/grid/ilc/users/phmag/LCIOOutput/PandoraCalibration".


I've not done any fitting with Root before, so for a first pass just centred the histograms by eye.
The constants I came up with are:

MokkaCaloDigi:
CalibrECAL=27, 81
CalibrHCAL=27.3

PandoraPFA:
ECALMIPcalibration=230
HCALMIPcalibration=31.5
ECALEMMIPToGeV=0.0045
ECALHadMIPToGeV=0.0045
HCALEMMIPToGeV=0.0353
HCALHadMIPToGeV=0.0353

I'll re-run the reconstruction of all the Z Higgs samples with these constants tomorrow.
