Attached are the ISC relief to HEPI; units are nanometers.  Finally, a complete tide cycle!  If only we had the iLigo predictor running.

Looks like we had plenty of head room on HEPI but it is interesting that the Yarm never went negative like the Xarm.  Not sure that means much at a day plus stretch.  Maybe some initial grab residual.  I expect it would start behaving after a few days lock
