In an effort to help the ISC crew use the seismic platforms I looked at ITMY performance today with the various blends and levels.  That is still ongoing though.  Meanwhile, since Stefan is able to lock his PRMI with the ISIs off, I propose that the ISI position loops do not do enough positioning to matter (HEPI is another story.)  So in an effort to make the ISI turn on more 'one button', with the ISI off I loaded the current positions in to the position loop targets.  With the position loops not doing much then, the Isolation can be turned on with the one button.  That isn't to say the ISI won't drift somewhere again too far, but for the moment at least it is 'one button.'  You can look at the first plot of trends to see what changed.  Most changes are very small but RZ is maybe 2urads.  Maybe significant but again, if the alignment is OK with the position loops off, these should be just fine.

So I brought the ISI up to Hugo's configuration of 6 Dec.  Not that it can't be improved or that there are no problems but at least the BLRMS looks pretty good, I think a lot better than turned off.  This configuration is 250mHz blends on Stage2 with T250 blends on stage1 except X & Y with T100mHz.44NO.  This is with level3 controller.  The script actually engages the boost2 rather than boost3 (heard that before haven't ya) but I really didn't see a difference at higher blends when I switched it to boost3 so I don't think it matters.

Again, we certainly need to improve these ISI performance, another day.
