Dave,

Thanks for the values, definitely a good starting point.

Regarding these 2 PVs listed under the DBX that you highlighted.
B_TORUS:LN2:TC8559F
B_TORUS:LN2:TC8559M

Those are both on the Torus LN2 screen. I was just copy and pasting from the instrument checkouts and that's what section they're under for both of the magnets.

If the CP & SC LL sensors for the Torus are important the checkout should be updated and not just have it on this list, but I'll add them to the script in the assumption they do get added.
