[SudarshanK, SheilaD]

We were able to stay locked with lower DHARD Gain last time (LHO alog #55526) ans Sheila made some changes to the DHARD filter yesterday ( LHO alog #55556). We took a regular sensing function measurement  to make sure the filter change has not affected our calibartion. We also made another sensing function measurment with a lowered DHARD Pitch gain (from -30 to -10). Both  measurements are saved at the following location below. Analysis to follow.
