Agenda

  1. Siyu: Update on HRS Optics[1]
    • Guido: how was dp/p calculated ? Siyu: it is a fitted sigma over p.
    • Siyu: The little bump in the middle of H20 spectrum is the first excited state of oxygen.
    • Cip: looks like there is a systematic offset in Sieve residual. Siyu: we are still trying to understand this.
    • Siyu: for raster correction, we didn't modify the database
    • Guido: You can also use one of the EPICS variable for raster correction , I can email you the info.
  2. Cip: Radiation dose on PREX quartz haplog:4064
    • PS: Does Qsq weighting matter?
    • KK: I think Qsq should be small effect. If we have pulse height distribution for the entrie run, it would be useful.
  3. Tao : pitt level null asymmetry [HAPLOG 4066]
    • dithering corrected double difference was not averaged by 1/2 and that is the reason why the error bar is twice big.
    • null asymmetry is calculated with equal weight between IN and OUT half-wave plate states, so that the error bar is the quadrature sum divided by sqrt(2)
