*Prior to July 10, solenoid angle was incorrect by 3 degrees https://logbooks.jlab.org/entry/3702542
*July 10 evening - after Run 3143 - solenoid angle fixed by injector group (was 89deg, put at 91.2deg)
*July 11 morning- after Run 3175- Table changed to also have solenoid =91.2 (for VWein 88deg) in addition to having solenoid =86deg (for VWein -89deg)
*changed the AposU and AposV voltages july18th,attached picture is a history of what we had until this day  in Figure 5

*July24 start of swing: Spin dance performed and HWien angle setting changed from -15.5deg to -13deg.
*July 31 documenting the settings before attempted 10nm move : up through slug23.

*Aug 1, slug 24 and 25. After 1 run in slug 24, changed AposV to try to cancel position differences. https://logbooks.jlab.org/entry/3713312. IHWPin: AposV=-385 --> want delta -20nm = +400counts --> new AposV =15. IHWPout: AposV=163 --> want delta +20nm = -400counts --> new AposV =-237
*For slugs 26 -65 used above nominal AposU/V settings: IHWPin: AposU/V=768/-385,AposU/V=1147/163
*Aug 25, starting with slug66-slug71, implemented the following change:
**IHWPin: AposU/V=768/-385 ---> new AposU/V=685/-678 (change AposU by -83 counts, change AposV by -293counts)
**IHWPout: AposU/V=1147/163 ---> new AposU/V=1176/465 (change AposU by +29 counts, change AposV by +302counts)
*Aug27, starting with slug 72, implemented:
**IHWPin: AposU/V=685/-678
**IHWPout: AposU/V=1176/465---> new AposU/V=1205/767 (change AposU by +29 counts, change AposV by +302counts)
*Aug29, starting with slug 74, implemented:
**IHWPin:  AposU/V=685/-678 ---> AposU/V=768/-385  (change AposU by +83 counts, change AposV by +293counts)
**IHWPout:  AposU/V=1205/767
