# Introduction
|
|
|
|
This is the analysis package for the SOLARIS DAQ. It is supposed to be the analysis path for the SOLARIS DAQ.
|
|
|
|
The folder struture is
|
|
|
|
Analysis
|
|
├── README.md
|
|
├── SetupNewExp // bash script to create new branch and raw data folder
|
|
├── SOLARIS.sh // bash script to define some env variable and functions
|
|
├── Armory // analysis codes, independent from experiment.
|

├── Cleopatra // Swaper for DWBA code Ptolomey and simulation

# ROOT issue
|
|
|
|
We are still using TProof for parallel calculation. TProof is not pre-compiled since 6.32+. And 6.30 only precompiled for Ubuntu 22.04. So, for system using Ubuntu 24.04, user must precompiled to root in order to work.

# Analysis & Simulation
|
|
|
|
The Armory/AnalysisLib.h constains many small but handy functions.
|
|
|
|
All class headers are started with Class*.h
|
|
|
|
The classes **DetGeo**** and **ReactionConfig** are fundamental for loading the detectorGeo.txt and reactionConfig.txt.
|
|
|
|
Both txt file support empty lines, and up to 2 settings. The reason for that is for dual-array configuration. It has potentail to extend and include more settings. But it is two now, one for upstream array (reaction) and downstream array (reaction).
|
|
|
|
The **TransferReaction** class is only use one of the reaction from the reactionConfig.txt.
|
|
|
|
```C++
|
|
TransferReaction::SetReactionFromFile("reactionConfig.txt", ID); // ID = 0 or 1
|
|
```
|
|
Same for the **Helios** class
|
|
|
|
```C++
|
|
HELIOS::SetDetectorGeometry("detectorGeo.txt", ID); // ID = 0 or 1
|
|
```
|

# Event Builder
|
|
|
|
The EventBuilder is at the armory. It depends on the Hit.h and SolReader.h.
|
|
|
|
## Hit.h
|
|
|
|
The Hit class stores a hit (or a data block)
|
|
|
|
## SolReader.h
|
|
|
|
The SolReader class read the sol file. It can be loaded in CERN ROOT alone.
