NA64 Data Processing Software Framework

This pages contain a reference to the software framework developed for data processing at the NA64 collaboration (CERN, SPS).

• Start with Tutorial if you would like to get feeling on this software (access to LXPLUS is needed).

• Refer to Standard Handlers Library to find reference on a particular handler or data structure for the analysis
