Currently the West Arc LCW, East Arc LCW, and South LINAC LCW Dissolved Oxygen (DO) readings are inoperable due to failed Honeywell sensors. LERF LCW DO reading is currently incorrect due to a failed pressure regulator that has isolated flow to the sensor itself. [figure:1] Above shows a screenshot that indicates the readings on the LCW commander screen that are incorrect.

Collected Energy Spread data over the long weekend. Data looks pretty good at about 98% good fits, with chi squared staying well below 0.5. Figure 1 shows the energy spread calculation during a gang phase change. Data gets noisy and varies with the Linac energy. When the phases are adjusted the energy spread drops, and then tightens up. Figure 2 shows a very similar picture.

Figure 3 shows the analyzer screen. I have a counter going of the number of good and bad fits that it is calculating. Out of nearly 73,000 since Friday it has only 1191 bad fits.
