LVEA/VEA temperatures

The weather has been somewhat violent this weekend. Daniel was asking about the temperatures in the LVEA/VEAs so I attach a recent plot.

Note that the ZONE Average is the LVEA average of ~64 sensors so I also include the worst looking zone, ZONE3B, which is the Y beam manifold area. The most remote sensor of this zone is down by the cryopump near the exit vestibule - this sensor is affected by north winds which leak through the doors. Perhaps an oplev in that region is suffering.

YEND is not as stable as XEND.
