The set of runs with dedicated configurations (lacCalib_**, flecalib_*,fheCalib_**), has been collected during July 4-7, 2008 allowing to extract the calibration curves for LAC, FLE,FHE thresholds.
ULD thresholds were calibrated on the basis of all available runs having
- nominal ULD settings (5% below the saturation:nomSciOps,calibOps,vetoCalib,bkgNadir,bkgPrescaled) or
- low ULD settings (10% below the saturatinconSciOps,hldCalib,conBkgNadir,conBkgPrescaled).
From the measured threshold values for low and Hi(Mid) settings and the DAC settings, knwo from configuration files, the linear model (thresh = slope*DAC+offset) was defined for each calorimeter crtystal end and each threshold type.
