Photodetectors
See JGW-D1402986 for location of photodetectors. See this Google spreadsheet for list of photodetectors
Modulation frequencies are listed in MIFIOOInterfaces.
- iKAGRA configuration (PMC: fPMC sideband / FRC: fIMC sideband / IMC: fIMC sideband, with ASC / FPMI: f1 sideband, without ASC / no ISS)
- bKAGRA configuration (PMC: fPMC sideband / FRC: fIMC sideband / IMC: fIMC sideband, with ASC / DRFPMI: f1,f2,f3 sidebands, with ASC / ALS: fALSX,fALSY sidebands, without ASC / with ISS)
