Pre-history of graphical applications
"All creatures great and small..."
LCLS
Most of them implemented in python using PyQt widgets and graphics in matplotlib
- calibman - calibration constant producer and manager, motivated by Amedeo Perazzo
- hdf5explorer - hdf5 file browser, motivated by Marc Messerschmidt
- corana - pipeline control and presenter for time correlation analysis, motivated by Marcin Sikorski
- loggrabber - weblogger population tool, motivated by Igor Gaponenko
- plims - image plotter
- med - mask editor
- iv - image viewer with PyQt graphics
- geo - PyQt in C++ - geometry alignment tool
LCLS-II
All of them implemented in python using PyQt widgets for GUI and graphics
- calibman - calibration constant monitoring and management in MongoDB
- hdf5explorer - survived part after LCLS
- timeconverter - converter between UNIX epoch seconds and human readable date-time
- screengrabber - screen grabber - survived aftyer LCLS loggrabber
- DAQ Control GUI
- iv - adapted from LCLS almost as is
- med - this project, official approval date 2023-05-23
