      Description

      The added "4 sigma outlier rejection" test in jointcal produces different values on centos6, apparently failing to reject 2 outliers that are rejected on other architectures. This is causing jenkins failures in jointcal.

      I've installed a centos6 docker container and I'm going to try to reproduce the problem there and use it for debugging. Figuring out which outliers are not being rejected is the first step. Determining why is the next step.

      The "end of fit" numeric differences are:

      centos6:

      jointcal INFO: Fit completed with: chi2/ndof : 1509.83/3684=0.409833
      

      macOS/Ubuntu/centos7:

      jointcal INFO: Fit completed with: chi2/ndof : 1506.7/3682=0.409207
