High-Frequency PCALX Injection Moved from 2001.3 to 2501.3 Hz
J. Kissel 

Since Jenne was able to get a beautifully long 6+ hour lock stretch last night (see LHO aLOG 28109), I've moved the PCALX high frequency calibration line frequency up to 2501.3 Hz. I've also increased the amplitude of the line to 40 000 [ct] of excitation in H1:CAL-PCALX_PCALOSC1_OSC_SINGAIN. 

I'm not *sure* it matters (since Kiwamu just recently updated the OMC DCPD whitening filter compensation; see LHO aLOG 28087), but let's be mindful that Jenne had added a stage of OMC whitening during that long lock stretch. It looks like she turned on the whitening right when the inspiral range jumps from just under 40 to just under 50 Mpc, so we should just consider the whole lock stretch having the first stage of whitening ON. 

I've accepted the new frequency (and increased amplitude) in SDF under the OBSERVE.snap file.
