Typical forms of userData
In addition to the points made above, there are a few more section to add if you are adding "userData" (reduced area detector data). SmallDataProducer_userData.py has examples for the most standard requests. Parameters that are important for the production (ROI boundaries, centers for azimuthal projections,...) are stored in the "UserDataCfg" subdirectory.
A most current example of a producer file that show how to add both "pre packaged" feature extraction as well as more free form user data can be found in github:

Each of the supported feature extraction/data reduction mechanism is described in their own subpages.
