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 type of the parameter depends on the release. Starting with ana-0.13.10, a TimeTool::DataV2 object in put in the event store. ana-0.13.3 put a TimeTool::DataV1 object in the event store. This is the preferred method to retrieve the data that TimeTool.Analyze writes. The module also writes its output as a set of doubles, and can optionally be written as a set of ndarrays to help with C++ to Python conversion. To enable this, set the option

put_ndarrays=True

to the config file. However this is not neccessary in releases after ana-0.13.3In ana-0.14.4 and later, this is how one gets the data, a TimeTool::DataV2 object. Older releases would also add the output as doubles or ndarrays, but this is no longer the case with ana-0.14.4 and later.

Controlling Laser/Beam Logic

...

then TimeTool.Analyze would treat the beam as on and the laser as off for every event.

Following the steps of Analyze

A general feature of psana is to control the level of output that differnent modules cary out. To see the trace and debug messages of TimeTool.Analyze, set the following environment variable before running your code

MSGLOGCONFIG=TimeTool.Analyze=debug

Starting with ana-0.14.4, you can also set the following configuration options:

[TimeTool.Analyze]
eventdump=True

This adds a number of intermediate calculations into the event store. The TimeTool package includes a Python module that will look for these results and plot them. To use this module, include it in the Psana module chain after TimeTool.Analyze, i.e:

[psana]
modules = TimeTool.Analyze TimeTool.PlotAnalyze

and then configure PlotAnalyze as follows:

[TimeTool.PlotAnalyze]
tt_get_key = TSS_OPAL
tt_put_key = TTANA
fignumber = 11
pause = 1

Module Check

a module that retrieves results from the event for either the above module or from data recorded online.
