re my 14373 entry, I figured I could correct these to the T1000388 even though there is a "Check the signs" Note in the doc as Fabrice says we'll just change the signs in the sym filters.
The matrix had correct elements in the primary transformations; only some of the cross coupling elements were variant. I went ahead and ran the populate matrices medm script. It crashed as it tried to load CPSALIGN values which are not in the data file. Makes me wonder how the GS13 & CART2ACT values got loaded before... So, I moved the CPSALIGN load section to the end and ran the script again. I then confirmed all the matrices complied with the T1000388--all good. Then confirmed the ISI still isolated--yes.
Then with the ISI just damped and HEPI not isolating( no Pos loops,) I drove HEPI in Z with a random noise signal band passed between .1 and 1 hz. Monitoring the HEPI L4Cs and the ISI Stage0 L4Cs, see attached, it appears that the vertical sensors are out of phase. So it seems we need that sign change in the SYM filters.
Made and committed safe.snap file.
Commissioners wanted the machine back before I could do other dof measurements, maybe I can do them with passive TFs. Either way, later.
Here is some horizontal data. I drove HEPI RZ but since the ISI L4Cs go to the Sensor Correction bank, it only has X Y & Z. So, here I look at the L4CINFs, the tangentially oriented sensors should be seeing this RZ. Compared to the vertical data above, I drove 4x as hard to get the coherence higher(still kinda poor.) It may not say the same thing, but, based on the phase, the signs are the same. Of course now this is before the input filters (I should have grabbed the _OUTs but too late for this run) much less the L4C2CART matrix so I'm really mixing apples and applesauce.
