Agenda
- 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.
- 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.
- 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)
Analysis projects
- BCM double difference study
- BPM resolution
- Pedestal / Normalization BCM history
- Events/ Patterns Counter
- Dithering sensitivity/Quality re-check
- Grand statistics re-check
- Linearity check
