Constructor & Destructor Documentation

VoltCalibrator::VoltCalibrator

(

)

VoltCalibrator.cxx

Implementation of class VoltCalibrator for the calculation of PMT high voltage settings.

Input: Three files are needed on input for this macro. They correspond to the relative gain vs HV data, the current HV settings and the required relative gain adjustment. These three files can have arbitrary names (and extension). They are identified with the methods "setRefFile", "setGainFile", and "setVoltInputFile".

Output: One file is produced on output. Its name is arbitrary and and must be set with the method "setVoltOutputFile".

Note: There are no default files and file names. All four file names (3 input, 1 output) must be set.

Operation: File names must be set with the modifier methods described above. The actual calculation is performed by the "process" method. The calculation first proceeds with the instantiation of a GainVoltCoeffCalculator wich reads in the calibration data and calculate for each PMT the gain coefficients. (see file GainVoltCoeffCalculator.cxx for documentation on the specifics on that calculation) The GainVoltCoeffCalculator instance is then used to process the calculation of new voltage settings. This first involves reading the current voltage settings as well as the requested RELATIVE gain adjustments.
