J. Kissel, E. Hall, E. Goetz I'm reconciling the SDF system for PCALY, and I've found a difference in the amplitude of the 331.9 Hz line. After speaking with Evan Hall, he had been commissioning with the line a month or so ago with an abnormally large amplitude of 30000 [ct] (see LHO aLOG 28702), and accidentally left it in place. Since then, someone had blindly accepted this value in the SDF system. I've now reverted it to the O1 amplitude of 2900 [ct] (see e.g. LHO aLOG 27981).
