91   * In the moment all measurements are taken and the weighted mean is calculated.   * The calculation of beta[13] is now modified:
92   * Note that the weights are just simple overall results for S1-S3, S2-S3, and S1-S2.   * We check the individual weights for artificial TDC values, then calculate
93   * Artificial measurments are not treated correct, (since there is only one real   * am mean beta for the first time. In a second step we loop again through
94   * measurment the weight should be different then for two meassurments).   * the single measurements, checking for the residual from the mean
95   * The beta calculation will be improved in the next release.       * The cut on the residual reject measurements > "x"-sigma. A chi2 value is
96     * calculated, furthermore a "quality" value by adding the weights which
97     * are finally used. If all measurements are taken, "quality" will be = 505.
98     * A chi2 cut around 3-4 and a quality-cut > 400 is needed for clean beta
99     * The Level2 beta[12] which is derived in the fortran routines uses: 10.,200.,20.
100     * This is not a very high quality measurement. One can re-calculate a new beta[13]
