class HMdcDeDx: public HParCond

 destructor

 prints the parameters of HMdcDeDx to the screen.

 intitializes the container from an input

 writes the container to an output

 Puts all params of HMdcDeDx to the parameter list of
 HParamList (which ist used by the io);

 returns the shift in ns for sector,module,impact angle (0-90)
 and distance from wire (mm). For distances larger 10 mm 0
 is returned.

 returns the shift sigma in ns for sector,module,impact angle (0-90)
 and distance from wire (mm). For distances larger 10 mm 0
 is returned.

 returns the shift in ns for sector,module,impact angle bin (0-17)
 and distance from wire bin (0-99).

 sets the shift in ns for sector,module,impact angle bin (0-17)
 and distance from wire bin (0-99).

 returns the shift sigma in ns for sector,module,impact angle bin (0-17)
 and distance from wire bin (0-99).

 sets the shift sigma in ns for sector,module,impact angle bin (0-17)
 and distance from wire bin (0-99).

 Puts the measurement values into increasing order.

 calculates dedx of a MDC segment by doing normalization for
 impact angle and distance from wire for the fired cells of
 the segment. The measurements are sorted in increasing order,
 the mean and sigma is calculated. Afterwards the truncated mean
 according to the set window (in sigma units) arround the mean
 is calculated and returned as dedx. Mean,sigma,number of wires before
 truncating,truncated mean,truncated mean sigma and number of wires
 after truncating can be obtained by the returned pointers.
 Different methods can be selected:
 vers==0 : Input filling from HMdcSeg (wires, thrown out by the fitter are ignored)
 vers==1 : Input filling from HMdcClusFit (wires, thrown out by the fitter are taken into account)
 mod==0  : calc dedx from 1st module in segment
 mod==1  : calc dedx from 2st module in segment
 mod==2  : calc dedx from whole segment (default)
 returns -99 if nothing was calculated

 Fills array of measurements from HMdcSeg and returns the number of fired wires in Segment
 The single measurements are normalized by impact angle and distance from wire. Only the first
 50 wires in one segment are accepted. Corresponds to method 0 in calcDeDx(......, version)

 Fills array of measurements from HMdcSeg and returns the number of fired wires in Segment
 The single measurements are normalized by impact angle and distance from wire. Only the first
 50 wires in one segment are accepted. The input is filled via the HMdcClusFit container,
 which contains all wires in a Segment before the Segment fitter starts. The wire objects
 are stored in HMdcWireFit objects. Wires thrown out by the fitter will have weight==0.
 These wires will not be filled into the output HMdcSeg. In this method all wires will be used
 to calculated the dEdx as difference to fillingInput(HMdcSeg* seg,Float_t* measurements).
 As this method uses data container of mdctrackD which are not created by default, the user
 has to make shure this containers exists and are filled.
 Corresponds to method 1 in calcDeDx(......, version)

 returns sigma from the Float_t array of nWire measurements with a mean value mean.
 Values equal to -99 are ignored.

 returns the mean value from the Float_t array of nWire measurements.
 Values equal to -99 are ignored.

 loops over the measurement array with nWire values and puts values to
 -99 if the measurements are outside the wanted window arround the mean value mean
 (set with setWindow() (sigma units)).
 The procedure keeps at least a number of minimum wires set with setMinimumWires().

 calculates 2 coordinate points from segment

 Calculates the dEdx (MeV 1/g cm2) of an particle with GEANT ID id
 and momentum p (MeV) for He/i-butan gas mixture with He fraction hefr
 (He (hefr) / i-butan (1-hefr)). The fomular is taken from PDG and doesn't
 include the density correction term. The values for the mean excitation
 energy are taken from Sauli.

 creates a TGraph for particle with GEANT ID id and
 and He/i-butan gas mixture with He fraction hefr
 (He (hefr) / i-butan (1-hefr) dEdx vs p,beta,1/beta2 or betagamma
 depending on opt (p,beta,1/beta2,betagamma). exchange=kTRUE
 will exchange x-axis and y-axis.
