PAW is conceived as an instrument to assist physicists in the analysis and presentation of their data. It provides interactive graphical presentation and statistical or mathematical analysis, working on objects familiar to physicists like histograms, event files (Ntuples), vectors, etc. PAW is based on several components of the CERN Program Library. Like CERN Program Library PAW usage and/or redistribution is granted under the terms of the GNU General Public License. For any questions about PAW contact Paw.Support@Cern.Ch or send a bug report. You may also find useful informations in the cern.heplib news group.

(last update: February 6th 2013)
Frequently asked questions are listed here as well as answers to them. A list with some usage statistics is also available. A file containing all the FAQs is also available (useful for a printing purpose). You can try also the CERNLIB FAQs. The PAW FAQs are regularly reordered according to the number of accesses each one gets. So, do not add a particular FAQ in your book-marks because it may point to an another FAQ after some time. It is recommended to always use the FAQ page's search facility to find a particular FAQ.

If you are not familiar with PAW and want to learn how to use it, this is probably a place to go. This tutorial has been modified to take into account the latest Ntuple queries processor capabilities. Therefore it is valid only for PAW versions greater or equal to 2.07. The old version of the PAW tutorial, using the previous version of the Ntuple queries processor, is still available. The sources of the tutorial examples are also available. Some other tutorials or help about PAW can be also useful to learn more about the system.
PAW reference manual
(last update: May 21th 2001)
The PAW reference manual (equivalent to the online HELP) is the complete description of all the PAW commands. The PAW User's Guide is available in Postscript format (1.05 Mbytes). All the CERNLIB manuals are also available. The man page gives the various options which can be used when you start PAW.
Down load
(last update: January 21th 2002)
To obtain pre-installed binaries of the current and latest version of PAW for different architectures and operating systems. This page also gives the list of the platforms on which PAW is supported by the CERN program library.
