Attached a couple of plots straight from MLCR EPICS archiver. Didn't have any time so picked PV and time interval at random...
Should be possible to repeat via remote access or PPD instance .

Last Monday I checked the mapping of EPICS PV's on to the EPICS EDM panel (arbitrary historical screenshot):
Columns match the screenshot: [PV name] ; PV:STA ; PV:BX ; PV:BY ; PV:BZ ; PV:B ; PV:B.EGU ; PV:STA.RVAL (?)
Rows:- SSU:
- MICE-SSU-HP-77
- MICE-SSU-HP-65
- MICE-SSU-HP-67
- MICE-SSU-HP-79
- SSD:
- MICE-SSD-HP-73
- MICE-SSD-HP-72
- MICE-SSD-HP-66
- MICE-SSD-HP-80
- External:
- MICE-CHAN-HP-01
- MICE-CHAN-HP-02
- MICE-CHAN-HP-03
- MICE-CHAN-HP-04
I was expecting to cross-check the description (implying location) of each PV against the [[cm:SystemSpreadsheets|ALH spreadsheet]], but the Services/Environment one doesn't have the description column filled out.
Tom Lord (at CM57 ) avoids sensors 66, 67, 80 (slide 10).

Pulled some stuff from the Archiver. Probably the colour scheme is wrong.
Not sure why the field changes independently of the current, e.g. see the beginning of CoolChan-SSU-2017-02-2_A.png
I've done some plots that include the Match coil currents, CoolChan-SSU-2017-02-2_E.png , and also SSD, CoolChan-SSU-2017-02-2_C.png , and it doesn't look to be down to mislabelling.

Also, the FC ramping up can be seen to have a small effect in CoolChan-SSU-2017-02-2_G.png .
Looking at CoolChan-SSU-2017-02-6_D.png the field in SSU is between 3.0348 and 3.0351 T over the entire cooling channel setting, i.e. stable to better than 0.01%.
Looking at CoolChan-SSU-2017-02-2_D.png it looks like the current in SSD is noisier.
