We have recently reduced the ETMX ring heater by 0.1 W to avoid the 80 kHz PI. As a result, our buildups have increased slightly and we have been operating closer to 440 kW. We ahve also had much shorter locks than we have had in the past operating around 430 kW. Looking at the power and lock trends, our longest locks occur when the circulating power is slightly lower. This small variation in circulating power can result from slightly different input powers every lock from how the ISS second loop closes. Jenne and I think this is enough evidence to drop the PSL input power by 1W. We will now operate at 75W input from the PSL, which should bring us closer to the 430 kW operating power that works best for us.

The requested power level for NLN in lscparams is now 75W. I have loaded the ISC_LOCK, IMC_LOCK and LASER_PWR guardians accordingly.
