1 LaVue is a live image viewer maintained by DESY's FS-EC ([[FS-EC main page>>url:https://confluence.desy.de/display/FSEC/LaVue+-+GUI+Layout||shape="rect"]]).
2 At FLASH we use [[conda enviroments>>doc:IS.Working with Anaconda Python]] and LaVue polls DOOCS images via [[pydoocs>>url:https://confluence.desy.de/display/FLASHUSER/PythonDOOCS||shape="rect"]].
