#### Structure of processed data ####
TTree structure of the processed data is illustrated in the following.
Tree name: "tree".
Inside one can find a variety of branches.
In 2018 we had N = 20 channels read. 5 DRS4 Boards x 4 Channels each. Each channel is configured to output 1024 samples.
Raw data is stored as a vector<float> in branches called 'RawCn' and 'Cn', where n is an element { 0, ..., N-1 }.
Each branch RawCn and Cn will be of size 1024 (corresponding to the number of samples).
Therefore for each event we have N vectors of size 1024.
RawCn corresponds to the "raw" output, what one would see on the DRS scope.
Cn corresponds to processed output, as determined by rdcaqAnalysis.
One can take the RawCn and reprocess it as they wish using JCaPA analysis methods (or implementing new ones).
Also, in the tree, there are branches that come from rcdaqAnalysis which have information on the output of each channel.
These are branches such as MaxCharge. Lets say there are M of them.
These are vectors of size N, you will have one piece of information for each channel. Be it max charge, or pedestal rms, etc.
Here you have information from rcdaqAnalysis depending on how it was configured. The user can use this and or do their own processing from the raw data.
Depending on how many pieces of processed info are saved from rcdaqAnalysis, you will have M vectors of size N.
Summarizing, there are
N branches of size 1024 for the channel waveforms.
and
M branches of size N for the processed data from rcdaqAnalysis. M is an arbitrary number.
