 Description   

Looking xcu_b2__vistemps table on archiver, I think values for mangin, detectorbox, and spiderrod is swapped: i.e., mangin looks spiderrod, spiderrod looks detectorbox, and detecotbox looks mangin.

It looks like the channel are swapped on the hardware side.
Looking at the current values, I think just mangin and detectorBox are swapped but I could be wrong.

We have been here before with these b2 sensors, INSTRM-2131. Along with the discussion over whether two or three were swapped. Along with a question about b4.

Never followed up with the (hardware?) tests though. I remembered putting a swap in code, but that was for a pair of b2 amps in the ccdActor (INSTRM-1100).

I think I'd vote for three being wrong: (high, low, middle) vs. (middle, high, low). 143 and 151 are different enough to be distinguished.

Yes, sorry. I agree.
