a module that analyzes the camera image by projecting a region of interest onto an axis and dividing by a reference projection acquired without the FEL.  The resulting projection is processed by a digital filter which yields a peak at the location of the change in reflectivity/transmission.  The resulting parameters are written into the psana event. The default behavior is to write these values in as a set of double's. Unfortunately double's are presently not visible to Python scripts or modules in the psana framework. In the next analysis release (Starting with ana-0.13.1) these values can also written as a set of ndarray's, each with one double. These will be visible on the Python side. This can be done by 3, a TimeTool::DataV1 object will be placed in the event in addition to the set of doubles that have been placed in the past. A temporary solution for C++ to Python conversion was adding the option

put_ndarrays=True

to the config file. To use the features prior to that release, when adding the TimeTool package to your test release, do

This wrote the doubles as ndarrays, but this will not be necessary with ana-0.13.3.
