* Ti-Yen
* halo close to beamcenter makes hitfinding diffcult for SPI
* converting ADU to photons is sufficient for SPI

* Aaron Brewster
* reprocessing because of unkown crystal unit cell
* unit cell can drift during the experiment, depending on sample preperation

* Peter Zwart
* hitrate can be quite high for imaging can be up to 80%
* clustering algorithm for hitfinding
* stable beam and sample delivery required
* difficulties in converting ADU to photons for pnccd, rounding errors
* check photon conversion on simulated data, understand errors in conversion

 

Extra description detail from Anton Barty:

 

The question was: when do you of back over all the data.
