Adjusted QE3M03 HMIN from -375 to -100 (per SME), which is now equal and opposite from HMAX.

Zone was out of HV with cavity 1 and 5 bypassed and no faults displayed. Cavity 1 history has it needing a 2.5w amp since 08/25 and cavity 5 low KCCU at .65 a with 2 kv KMAV. All cavitities marked bad in cavity history but I think someone mistakeningly did this back in April after GSETing to 0.

With all but cavity 1 not communicating, we will have to again wait for shutting down CAMAC AND iocnl2 to diagnose this comm. failure in 1L13. IOC healthcheck doesn't show any failures when all the cavities in a zone are bypassed. No comm's in/out !

While initial harp swipes of 2H00A seemed good in y, and too large in x, and it should be simple to squeeze down x, trying various quads in both directions have not yielded desired results. We are going to take a harp swipe at 2C04 to make sure we don't need to adjust the 2C matching quads, then will likely backtrack to quad values from a few days ago or from CED.
