 * Standard usage is to read payloads ECLRefAmpl, ECLRefAmplNom,          *
 * ECLRefTime and ECLRefTimeNom and use them to derive payloads           *
 * ECLCrystalElectronics or ECLCrystalElectronicsTime                     *
 *                                                                        *
 * Alternatively, find new payloads ECLRefAmplNom or ECLRefTimeNom  to    *
 * keep ECLCrystalElectronics or ECLCrystalElectronicsTime constant       *
 *                                                                        *
 * Also performs a comparison of new and existing calibration values and  *
 * writes these to a root file.                                           *
 *                                                                        *
 * Payloads are read from localdb if present, otherwise from              *
 * ECL_localrun_data                                                      *
 * They are written to localdb with iov = exp,run,-1,-1                   *
 *                                                                        *
 * Usage:                                                                 *
 * eclElectronicsPayloads payloadName exp run [writeToDB]                 *
 * where payloadName = ECLCrystalElectronics, ECLCrystalElectronicsName,  *
 * ECLRefAmplNom, or ECLRefTimeNom                                        *

 * exp and run specify the start of the iov, and are used to read         *
 * the reference amplitudes and times                                     *
 * Option argument writeToDB = 0 to not write output to database          *
