Caption: Figure 9.

Temperature drifts in the spectrograph room (top panels) and vacuum chamber (bottom panels) before the HVAC system was upgraded (left panels) and after (right panels) over 48 hr periods. Sudden spikes in temperature in the spectrograph room resulted in very small spikes in the vacuum chamber temperature, but even after this was fixed, a temperature drift of 0.075 K per day persists in the chamber.
