class HMdcGeomParF: public HReconstructor

 Constructor for only one MDC

 Inits common defaults

				HGeomVector*& ang2,HGeomVector*& tra2,
				HGeomVector*& ang3,HGeomVector*& tra3)

 Sets the pointers to previous results of HMdcAligner.
 This function should be called in the macro

 Sets ascii output for results and debugging.

 Sets Root output

 Sets the Tukey constant in the weigth determination
 for 1 MDC target finder
 The function arguments are:
   cte   the initial Tukey constant
   step  the step between tukey calculations
   res   the tukey value for which the calculations on the output file are made
   end   the last accepted Tukey value

 Sets the init value
 for 1MDC target determination

 Sets targetFinder call for two modules

 introduce unit errors in Hits

 Fix a parameter set in minimization
 Z translation is always fixed for Minuit.
 1...6 parameter number (Minuit parameters begin in 0, then param+1)
 20    fixes translations
 30    fixes rotations

 Set the TTree from the HMdcAligner selection
 When fUseCut=kFALSE it is used a TClonesArray
 of Hits without cuts in the distributions peak fit

 Sets a cut in the 1 MDC target finder.
 Introducing a positive valu: the cut
 eliminates in the fit the low incidence angle tracks,
 trying to get more resolution in Z target determination
 Introducing a negative value: the cut
 eliminates in the fit the large incidence angle tracks,
 trying to eliminate fails in reconstruction due to
 larger distances between planes than in parameters
 or any tracking systematics in the reconstruction

 Sets a cut in the 1 MDC target finder.
 The cut eliminates in the fit the tracks closer
 to the beam line, which pushes the target estimate
 towards positive values of Z.

 From the relative rotation, get the euler angles (radians)

 From an Euler rotation (see Dahlinger paper for the convention)
 the euler angles are:
 euler[0] = atan2(rot(5)/sin(euler[1]),rot(2)/sin(euler[1]))
 euler[1] = acos (rot(8))    with possible change of sign
 euler[2] = atan2(rot(7)/sin(euler[1]),-rot(6)/sin(euler[1]))

 Only one MDC. Trying to find out the point where all
 tracks point to.

 Filling Hits of a frustum. Trying to find out the point where all
 tracks point to.
