Heat increase in the LVEA
I have increased the heat in the LVEA in sections 1A and 5 by 1 ma each.
End X is slow to respond so I have raised the heater to 11.5 ma and increased fan flow SF01 to 12 ma and ~11500 cfm.
I assume these temperature increases were well motivated, but I hope the affects of such increases were considered before hand, especially considering we're in the middle of a run. Small temperature variations can have noticable impact on the IFO, such as changing test mass suspension positions and/or acoustic mode frequencies.
It looks like "temperature" difference units are given in amps? What is the temperature as a functon heater current?
