1) add error message if Time between sucessive reads is zero.
    This should never happen.

2) Add the event number of that scaler read to the Scaler root tree
   The tree variable is evNumber

Added a check that fDeltatime>0 when calculating
charge and current.

   For a TrigDet associated with one spectrometer, call SetSpectName
   so that H.present or P.present can be found.
   For coin TrigDet, supply a list of event types for which warnings
   should be suppressed.

  Other missing energy def name changed to emiss_nuc
  Get secondary particle mass from the parameter DB
    instead of the spectrometer object

Switched X and Y rasters to make them consistent with epics left-handed coordinate system, and changed sign of x in fDirection() to make the beam position a right-handed system

  Don't use prefix to construct name

  It was a stupid idea

Edited CalculatePedestals() method to correctly fill rasters, and corrected typos in fYA_ADC and fXB_ADC when calculating the currents

  The Event handler can now be given any name.
    (Only one THcConfigEvtHandler should be instatiated.)
  Also:
     THcConfigEventHandler clears CrateInfoMap on Init.
     THcHitList caches FADC config on first event

Add _ti_ps_factors[] array with prescale factors computed from exponents

Add variable for the difference between the Hodoscope start time
and the ADC pulse time.

Select good adc hit based on window on this difference

Have variables fGoodPosAdcTdcDiffTime and fGoodNegAdcTdcDiffTime
which are the difference
between TDC time and ADC pulse time

Replace ADC pulse time cut with cut on difference
between TDC time and ADC pulse time to select
good ADC pulse.

Eliminate cut on fStartTimeCenter in selecting good
  focal plane times.

Add code for doing the vertical target position
   correction to the optics.

Fix mistake of add target offsets twice.

Fix mistake in units for the HMS Q3 correction

Add in offsets for xptar, yptar and delta

Add in delta correction as function of xpfp and central
  momentum for HMS. This corrects for a problem in setting Q3 current.
  There was an unknown zero offset in the Q3 current.
  This was determined by T. Horn in 2003.

  To do this suppression, a trigger detector object needs to know the
  name of spectrometer it is associated with.  By default it will get
  this name from the first character of the it's own name.  This can
  be overridden with the SetSpectName method.

  Each detector object will check the global variable X.present each
  event.  If X.present is false, it indicates that the parent
  spectrometer object determineted that this spectrometer is not in
  this event, and therefor reference times are not expected.  If
  X.present is false, then the reference time warning messages will
  be suppressed.

Add ability to cut on number of PE in Cherenkov when dumping events
  for TOF calibration

Add parameter fTOFCalib_cer_lo

Add ability to cut on track beta when dumping events
  for TOF calibration

Add parameter fTOFCalib_beta_lo and fTOFCalib_beta_hi

Parameters are optional. Default set to kBig or -kBig

THere was already a possible cut on Shower energy/momentum

Moved filling of  fNRegions from parameter to before the fRegionValue array
is defined. The code had been using default fNRegions=4 regardless
of vaule  of  h_num_regions in parameter file.

Add leaf dc.chisq which is the chisquared/dof of the golden track.

Add rawnorefcorrtime to THcDCHit which is the TDC raw without
the reference time subtraction.

Add variable rawnorefcorrtdc in THcDriftChamberPlane::DefineVariables

Modify THcDriftChamberPlane::ProcessHits to call GetRawTdcHit().GetTimeRaw
  and call THcDCHit with new extra argument for raw time without reference time
  subtraction.

Modified so that the fGoodPosAdcPulseTime, fGoodNegAdcPulseTime
  or fGoodAdcPulseTime is set to kBig

Modified THcShowerRawHit::SetReference to takeADC signals

Modified THcTrigRawHit::SetReference to take ADC signals

Modified THcShowerArray::ProcessHits so that fAdcTdcOffset add to frAdcPulseTime

Modified THcShowerArray::ReadDatabase so that defaults for fAdcThreshold etc
  are before gHcParms->LoadParmValues

  This is because it is offsetting PulseTime which is double and to
  be consistent with the other detectors.
