PAW Tutorial (before version 2.07)

The modified or suppressed examples are marked on the following list.

This tutorial gives an overview of the PAW functionalities. It is organised around four main topics:

• Vectors
• Histograms
• Ntuples
• Miscellaneous

Each example is linked to the next one. It is better to scan the examples in the proposed order.

A printable PostScript version, a compressed tar file of all the examples and a compressed tar file of the html pages are also available.
