 * These results are then stored with the "trkseqno" = -1.
 * If we use the track from the tracker, then the penetration points in the
 * scintillators are calculated, which defines the hitted paddles. For these paddles
 * we calculate then all the output.
 * Note: The artificial ADC values are stored as dEdx in the output, the dEdx will be
 * by definition = 1. However, the artificial TDC values are just used internally
 * and not stored in the output. But one can see in both cases which PMT has artificial
 * values using "adcflag" and "tdcflag".

 * \brief beta, 12 measurements for the 12  combinations, beta[13] is modified weighted mean
 *
 * The 12 measurements are S11-S31, S11-S32, S12-S31, S12-S32, and then analogue for
 * S2-S3 and S1-S2. 
 * The calculation of beta[13] is now modified:
 * We check the individual weights for artificial TDC values, then calculate
 * am mean beta for the first time. In a second step we loop again through
 * the single measurements, checking for the residual from the mean
 * The cut on the residual reject measurements > "x"-sigma. A chi2 value is
 * calculated, furthermore a "quality" value by adding the weights which
 * are finally used. If all measurements are taken, "quality" will be = 505.
 * A chi2 cut around 3-4 and a quality-cut > 400 is needed for clean beta
 * The Level2 beta[12] which is derived in the fortran routines uses: 10.,200.,20.
 * This is not a very high quality measurement. One can re-calculate a new beta[13]
 * using the L2-method "CalcBeta"
