class HMetaAligner: public TObject

 Called in the constructors to clear the variables

 Initialize the class.
 pFileName - is a name of an input file which consists of Ntuples
 iSector and iSystem define the detector. iSystem == 0: Shower, 1: Tof
 pParamFile and iRunId defines setup with parameters

 Initialize HADES & Runtime dB and load parameters for the specified detector

 Initailize PreShower geom parameters

 Initailize Tof geom parameters

 Open the file with the NTuple

 Set the start value for a parameter.
 iParam:
 0: dX
 1: dY
 2: dZ
 3: dRotX
 4: dRotY
 5: dRotZ

 Set start steps for the parameters

 Fix the parameter

 Release the parameters

 Release all the parameters

 Fix all the parameters

 Revers the fix flag for all parameters

 Set the MINUIT error value

 Set the maximum number of iteration for MINUIT

 Set the Tukay's constans.

 Normalize the chi^2 to the number of events taken into the account

 Should MINUIT try to improve the results ? The calculations are twice longer.

 Set the number of entries taken into the account (Not all from the input
 file). If i <= 0 then all events are taken.

 Copy the results from the previous iteration to the input parameters.

 Run the alignment procedure.
 bUseTukay defines if the Tukay's weights should be used.
 pOut defines a file with the output NTuples. pOut == NULL - no output file.
 iMethod: MINUIT minimize method:
 0 - MINImize
 1 - MIGrad
 2 - SIMplex

 Next iteration of the alignment procedure.
 Parameters as for runFit method.

 Print a table with all the results of the alignment procedure.
 If pFileName != NULL the output is redirected to the pFileName file,
 otherwise it is send to stdout.
 When (I) appears after the method name the minimization was improved.
 (Chw) after the Tukay's const. value means that the weight was changing.
 (N) after FCN means that FCN was normalized and (eS) means that
 all detectors resolutions was equal 11.

 Print the alignment results in a line.
 pFileName as for print method.

 Print the results as a HTML table's row.
 The order of the output: detector name, dX, dY, dZ, rotX, rotY, rotZ,
 number of hits not taken into the account / total number of hits, FCN.
 pFileName as for print method.

 Calculates the chi^2 from a hit

 Function called by MINUIT.

 Function called to write results of the fit to an output file: pFileName
