I looked closer at the RTDs, and they are all PT100s with the same resistance-temperature curve [Attachment 1]. So we might need to re-calibrate them.

The chamber is currently warming up, and I plan to cool down again on Monday to a) obtain data for the entire cooldown and b) see if this inner shield behavior is repeated.
