dune-pd-ana

A C++ analysis framework to estimate the performance of the DUNE Photon Detection System

In this repo

Here you can find macros (file.cpp in this folder) useful to plot the persistance of a set of waveforms, compute the Signal-to-Noise ratio from a calibration run, compute the FFTs of the electronic noise... In Macro_description.txt you can find a brief overview of what the macros do. "Header" contains the .hpp files where all the functions are delcared, divided in categories. The const.hpp file is the only one you should change to adapt the codes to your dataset: it contains all the parameters needed for your analysis.

The codes are desigend to run interactively in a ROOT session. To open the ROOT session you should run the following commands:

root
#include "const.hpp"
#include "/PathToThisRepo/pds-ana/Class/classe.hpp"
auto a = cla()

Where const.hpp must be in the folder where you launch the ROOT session. At this point, you can start play with a. Personally, I have a zsh alias to copy a template const.hpp in the current folder and to launch the session. (see scripts)

Get started

Whatever you want to do, the first step is to read the data. Be sure that your data are in a supported format, or write a function that store it in an std::vector<std::vector>. The data_format member allows yu to specify the function want to use with a simple tag.

a.data_format = "tag"
a.wf_file = "path/the_file_to_read"
a.memorydepth = #NumberOfTicksPerWf
a.prepulse_ticks = #NumberOfTicksToEvaluateTheBaseline
a.Persistence()

Check if everything is correct!

You should see something like: Alt text Keep going with the Enter command.

Hey, your pulse is negative! Let's invert it with:

a.invert = true/false

Now you should see something like: Alt text

If you are happy with this starting point, let's update the initial parameters of the class by:

a.update()

This modifies the const.hpp file, so that the next time you lanch a session you will resume from the last checkpoint.

Keep going! Run AverageWF(), find an integration window [int_low; int_up], run LED_Analysis() and look at the Images folder to have an idea of what else you can do.
