CP3's reservoir level is back on scale - reading around 97% full. I lowered the PID lower limit of LLCV to 15% open when it was ~99% full to measure percentage per hour to get a feel for how low the reservoir got over the weekend.
PID is programmed to hold the reservoir at 92% full. Once it drops to that level, PI will kick in.
This proves LIGO is not a hoax. Nobody could make this story up.
A story worth documenting! Can we warm up CP4 next? ;)
PI performance looks good. And there is no smoothing factor set. At 15% open on LLCV, rate of decline is 2.3% per hour given today's temperatures.
