Tue CP1 Fill. New code.

Tue Feb 25 10:17:54 2025 INFO: Fill completed in 17min 49secs

Today was the first run of the new code, which terminates the fill on rate of thermocouple temperature drop rather than dropping below a set limit. This will free us from having to manage the limit during seasonal changes.

TCmins[-144C, -140C] OAT (+11C, 51F).

For now the plot still shows the old -90C trip level. I'm working on a new plot which shows the rate-of-change channels.

I'll make a detailed alog about the new code with its associated MEDM, striptools and plots in the next few days.
