PAW software (Physics Analysis Workstation): PAW is an interactive utility for visualizing experimental data on a computer graphics display. It may be run in batch mode if desired for very large and time consuming data analyses; typically, however, the user will decide on an analysis procedure interactively before running a batch job. PAW combines a handful of CERN High Energy Physics Library systems that may also used individually in software that processes and displays data. The purpose of PAW is to provide many common analysis and display procedures that would be duplicated needlessly by individual programmers, to supply a exible way to invoke these common procedures, and yet also to allow user customization where necessary.
