Hydra - Checked tolerances of adjustments that were completed in Jan. 2017.
                1. Changed / decreased the tension for the relaxed fiber position. 
                2. Changed the cruise position from -1500 to -1600.
                       This is in response to the fiber being flexed while in the parked or stowed position.
                3. Checked and measured fiber / gripper gaps after picking them up off of the 
                       plate.
                4. Tested Hydra - parked all blue fibers from the previous configuration and completed
                       a blue circle without errors. Used both the fiborg test program and operational fiborg
                       program.
                5. Cleaned the dust off of the inside of Hydra, reduces particles that could decrease
                       efficiency of fiber inputs.

        Elevation / Azimuth Drives (Inspected and cleaned drive surfaces)
	               No wear / abrasions or rust evident
        Azimuth Balancing (Measured azimuth balance with a high precision level) 
                       Measurements agreed with previous / Hydra / ODI installed

       Nighttime Tests
              NOTE: Determined that Azimuth Motor 1 was not working during the
                          tests. Reset Master and Slave Power Amplifier after tests were
                          completed. (See Attached Plot of Azimuth Motor Currents)

              Pointing Verification - 12 point verification ( average ~25 arc sec)                               
              Pointing Map - Same fit as previous map with wrap in the west. 
              Tracking Test - 30 minute test - approx. error 1 to 2 arc seconds 
  		NOTE: Did not update pointing model with data from a single drive.
