The Bach Alignment Package

Bach is a common software-tool to align telescope-like detectors. It describes the complete analysis chain of a telescope detector, from simulation to reconstruction. It demonstrates the functionality of the MILLEPEDE alignment algorithm.

The user manual is available as an AIDA note

The source code is available via svn:

svn co https://svnsrv.desy.de/public/aidasoft/AIDAAlign/trunk/Tb Tb
