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

chris

• 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).

mark

• getting open cluster working in lab2 drp node

mikhail

chris

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

sioan

• led's are counting on FPGA eval board

chuck

• working on SZ absolute error of +-30 doesn't seem to affect indexing

clemens

• pgp in lab2

mark

• thinking about reusing astronomical package

mikhail

chris

• setting up test stand
• still understanding trigger vs. filter setting

silke

• distracted by turning things on

sioan

• moving from devel board to pgp card
• no progress on sxrk4816

chuck

• sfx: trying sz with 60 ADU
• spi: users like veto, binning, but not general lossy compression (e.g. sz)
• spi: data will be more sparse because of lower fluence (not true for sfx)

clemens:

• working on other stuff. need to pick out new project.
• handed off drp event distribution to mark
