Hall A Analyzer

h1. Wiki

h2. Introduction

This is the homepage of the main Hall A physics analysis software, "Podd". The software is an object-oriented, modular and extensible framework built on top of "ROOT":https://root.cern.ch. Classes are available for the most common analysis tasks involving data from the standard "Hall A":https://hallaweb.jlab.org experimental equipment, in particular the HRS spectrometers and detectors. Standard physics calculations for single arm (e,e'), conincidence (e,e'X) and photoproduction reactions are available, as well as for auxiliary tasks such as energy loss corrections, vertex position calculations, etc.

The included Software Development Kit (SDK) provides users with a rapid development environment for building experiment-specific extension libraries. One can quickly implement new detectors, physics computation modules and even entire spectrometers.
