Attached is a trend of the average LVEA temperature showing the daily ~0.2 deg C temp swing. The plot is for the month of August 2014 when we were finishing installation of the vertex. When we are vented and adjusting the EQ stops of a suspension we may see a ~0.06mm change in the gap of the EQ stops around the barrels of the PUM and Test Masses in the QUAD daily. (0.2degC change x ~0.3mm/1degC temp change = 0.06mm)
This is pretty negligible. Phew. However, this temp change pitches the suspension, so now I'll try to find out by how much. To be continued...
