This is the humble homepage of the main Hall A physics analysis software,
Podd. The software is an object-oriented, highly modular and extensible
framework built on top of ROOT.
Classes are available for the most common analysis tasks
involving data from the standard Hall A 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 optional 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.
A separate extension library is available for track reconstruction
in the BigBite spectrometer equipped with MWDC drift chamber planes.
Currently, major efforts are underway (1) to develop an improved analysis
framework jointly with Hall C
which will be based on the current Hall A software, and (2) to update Podd
for the more demanding analysis requirements of
12 GeV experiments.
Linux with the gcc 4 or higher compiler and GNU make,
or or Mac OS X 10.6 and up with Apple's command line tools for Xcode.
The compiler you use must match the one used to build your installation
of ROOT.
Moderate hardware (e.g. 2GHz CPU, 1GB RAM).
Linux and Mac OSX environments are detected automatically.
Ports to other Unix platforms should be straightforward.
Please see the Release Notes
and Installation Guide for details.
