Chuck:

• summer intern (utsab) working on sz absolute error compression
• working on photon conversion: with zwart and ruslan using det.photons()
• working on manifold embedding with hao-yuan for 2016 dataset (works for 2015 dataset)
• triggering options are time-of-flight and ROI/threshold on image (drifting background: need running average)
• hao-yuan looking at neural-nets for SPI hit-finding

clemens:

• working with cpo on data format inside DRP nodes
• can distribute at 3MHz on 4 core laptop

cpo

• looked at EPICS pvData with Murali
• ric and mark working on trigger and event distribution

silke

• focusing on lcls-1

• went to hutches and played around with DAQ interface to enable event veto
• worked on quick-and-dirty background-subtraction/thresholding algorithm:  numba: 2ms, c++: 6ms (not understood why c++ slower).

• getting open cluster working in lab2 drp node

• lab2 pgp loopback is running
• 0.5 Mpixel epix calibration is 30ms and peak-finding is about 60ms (although maybe likely our algorithm can be sped up).  doesn't bode well for 4MP epixM epixM at 10kHz in 2020.  looking into "quick and dirty" detector triggering algorithm:  simple background subtraction and thresholding
