 // Original Author Danek Kotlinski
 // Ported in CMSSW by  Michele Pioppi-INFN perugia
 // Added DB capabilities by F.Blekman, Cornell University
 //         Created:  Mon Sep 26 11:08:32 CEST 2005
 // Add tof, change AddNoise to tracked. 4/06
 // Change drift direction. 6/06 d.k.
 // Add the statuis (non-rate dependent) inefficiency.
 //     -1 - no ineffciency
 //      0 - static inefficency only
 //    1,2 - low-lumi rate dependent inefficency added
 //     10 - high-lumi inefficiency added
 // Adopt the correct drift sign convetion from Morris Swartz. d.k. 8/06
 // Add more complex misscalinbration, change kev/e to 3.61, diff=3.7,d.k.9/06
 // Add the readout channel electronic noise. d.k. 3/07
 // Lower the pixel noise from 500 to 175elec.
 // Change the input threshold from noise units to electrons.
 // Lower the amount of static dead pixels from 0.01 to 0.001.
 // Modify to the new random number services. d.k. 5/07
 // Protect against sigma=0 (delta tracks on the surface). d.k.5/07
 // Change the TOF cut to lower and upper limit. d.k. 7/07
 //
 // July 2008: Split Lorentz Angle configuration in BPix/FPix (V. Cuplov)
 // tanLorentzAngleperTesla_FPix=0.0912 and tanLorentzAngleperTesla_BPix=0.106
 // Sept. 2008: Disable Pixel modules which are declared dead in the configuration python file. (V. Cuplov)
 // Oct. 2008: Accessing/Reading the Lorentz angle from the DataBase instead of the cfg file. (V. Cuplov)
 // Accessing dead modules from the DB. Implementation done and tested on a test.db
 // Do not use this option for now. The PixelQuality Objects are not in the official DB yet.
 // Feb. 2009: Split Fpix and Bpix threshold and use official numbers (V. Cuplov)
 // ThresholdInElectrons_FPix = 2870 and ThresholdInElectrons_BPix = 3700
 // update the electron to VCAL conversion using: VCAL_electrons = VCAL * 65.5 - 414
 // Feb. 2009: Threshold gaussian smearing (V. Cuplov)
 // March, 2009: changed DB access to *SimRcd objects (to de-couple the DB objects from reco chain) (F. Blekman)
 // May, 2009: Pixel charge VCAL smearing. (V. Cuplov)
 // November, 2009: new parameterization of the pixel response. (V. Cuplov)
 // December, 2009: Fix issue with different compilers.
