Body: Fopt 7.9 completed successfully. The runtime settings include a sample count of 15, a minimum current of 4, and an operating regime of Standard with Excitation in 1S Region. The corrector and RF kicks applied were 0.488208 and 0.488208 volts respectively. The max. amplitude setting was 1 millimeters. The files for this run were saved in the directory /cs/opshome/hlapps/optics/diforb/26apr061719. The X and Y stability of the machine during the run was 0.062581 and 0.0642317 (mm) respectively.

Came in 8E match was downloaded. Beam still not on design according to the harp, yet it is smaller than before. Tried swiping IHA9E01 at several different gain settings and changing the position from where the scan begins, yet still the harp only produced noisy plots with no recognizable peaks. IHA9E01 needs to be repaired.

Recombiner procedure is only for differential orbit greater than 3mm. Our differential orbit is less than 3mm so we are going back to correct horizontal dispersion in 9L.
