===== Calibration =====
  -Put the bracket around the 2D-C arms and attach the spinning disk to the bracket.  Make sure the red dots on the bracket and spinning disk are side by side.
  -Align the disk so that the center of the big dot is right in the middle of the 2D-C laser.
  -Turn on the spinning disk.
  -Set the true air speed for the probe to 25 m/s.
