   5 # We have one ADD32rr measurement, and two measurements for SQRTSSr.
   6 # The ADD32rr measurement and one of the SQRTSSr measurements are identical,
   7 # and thus will be be in the same cluster. But the second SQRTSSr measurement
   8 # is different from the first SQRTSSr measurement, and thus it will be in it's
   9 # own cluster. We do reclusterization, and thus since there is more than one
  10 # measurement from SQRTSSr, and they are not in the same cluster, we move
  11 # all two SQRTSSr measurements into their own cluster, and mark it as unstable.
  12 # By default, we do not show such unstable clusters.
  13 # If told to show, we *only* show such unstable clusters.
