Attachment 1 shows a five and a half day minute-trend of the three temperature sensors. Logging started last Thursday ~ 2 pm when all sensors were finally deployed. While it appears that there is a 7 degree gradient along the XARM it seems like the "vertex" (more like ITMX) sensor was just placed on top of a network switch (which feels lukewarm to the touch) so this needs to be fixed. A similar situation is observed in the ETMY sensor. I shall do this later today.
Done. The temperature reading should now be more independent from nearby instruments.
