I. E10 (expect: S2-V3-like calibration ready for E10)

• Prior to E10, make
• DC calibrations and sign measurement
• representative hardware measurements (new dewhites, anti-imaging, coil drivers)
• open loop gain measurement
• update model, output reference spectra (olg, sensing, response, actuation), handoff to Sensemon
• ensure Sensemon has the information to give reasonable range estimate at the outset of E10 and establish IFO performance
• provide hardware injection group realistic actuation function as early as possible
• begin hardware measurements after freeze

II. S3 (expect: S2-V3-like calibration ready for S3, with all hardware measurements completed)

• all hardware measurements completed (model not necessarily including all subtle effects, just obvious ones)
• may revisit DC calibrations, etc if not satisfied with E10
• Autocalibrator upgrades:
• Swept sine version: better actuation function, NS-NS range, output cal file
• UGF version: fast determination of darm ugf, output model-based calibration and data products
• excitation channels
• would like to inject calibration lines on DARM_EXC for entire run
• requires new channel to be stored in frame and RDS, plus LSC code modification
• eliminate ETMY_EXC from frames/RDS
• inject long-term pulsar signal into ETMX_EXC
• if Autocal sweeps, do on ETMY
• runtime request
• first 8-hour shift of S3 for calibration measurements and cal line amplitude setting (may take less time)
• expect to have lengthy/problematic measurements such as DC ones out of the way prior to S3
• expect mid and end run calibration runs
• additional measurements include cross-coupling investigations
