We changed both the Pcal and DARM_CTRL excitations to the following (expected SNR with 8 sec FFTs in parentheses):
PcalY:
36.7 Hz at 360 cts. (90)
157.9 Hz at 575 cts. (41)
331.9 Hz at 2,320 cts (90)
1083.7 Hz at 24,000 cts (36)
DARM_CTRL
37.3 Hz at 0.31 cts. (90)
These are our best current estimate of what we will want to have for O1. We expect to make similar changes at LLO, with their calibration lines within a hertz or two of ours.
The other excitations (including those from the Xend Pcal) have been switched off. Snapshots of the relevant sections of the MEDM screens are attached below.
The total Pcal excitation range is about 42,000 counts so the 1083.7 Hz line uses about 60% of the range and the other three lines together use about 8% of the range.
