iocsl1b, 2, and 4 not taking micro set point saves
Ran Trim up/down to start hardening SL in anticipation of running beam. Many zones tripped as was somewhat expected due to a reoccurring issue of clamps setting to 0V and loop switches opening for zones set to expert mode following ioc reboots. This is a known issue under investigation by the Software group.
In addition several klystron voltages restored lower than expected (frequently reducing the kccu current from the klystron to zero and preventing cavities from turning on).

Tune beam roughl steered to ILD for rayTrace testplan
I left the HWien as found at +42 degrees. I roughly set the Injector energy manually with 0L04 and the chicane BPMs. I think this will be good enough for our purposes tonight. I'll do a viewer walk next to make sure the beam isn't completely stupid. I understand that Yan will still need to further optimize beam to the ILD.
