- This repository aims to provide a fast reconstruction of data acquired with the H4DAQ mainly with the CAEN V1742 Digitizer
- The main program is the H4Reco ntuples producer which can be easily configured through the input cfg file (examples in cfg/).

- Comment lines start with a ‘#’ followed by a space
- blocks are defined within
<block>...</block>
- each key (line inside a block) can take an unlimited number of options
- The
importCfg
key allows one to express an unlimited number of other cfg files that are read sequentially before the current one so that blocks/keys that are present in more that one file are overwritten.
- The main executable.
- The idea is to run multiple plugins, each dedicated to a specific task, i.e. reconstructing hodoscope hits, digitizer waveform.
- H4Reco takes two arguments: a cfg file and the run number that overrides the one specified in the cfg file
- Each Plugin has three methods that are called by the main program:
Begin()
: is called once after the plugin instance is created and before the first event is processed. Takes two arguments: aCfgManeger
with all the option loaded in H4Reco and aindex
dedicated to synchronize the plunging trees with the main one.ProcessEvent(..)
: called once for each entry of the H4Tree under analysis. It takes three arguments: the CfgManager with all the options, a reference to the analyzed H4Tree and the list of plugins loaded in the H4Reco plugin sequence. The last arguments allow to share data between plugins through the plugin methodsRegisterSharedData
andGetSharedData
.End()
: called at the end of the H4Reco processing, after all the events have been processed.
- A single output file is produced, it contains the main tree “h4” to which all the trees registered by the
plugins as “permanent” are linked (using
TTree::AddFriend()
). - More information can be found in
