Built-in Analysis Tools

SNOMAN contains analysis tools that allow you to do significant analysis without writing a line of code -- see the chapter "Adding Code to SNOMAN" when you want to do that. These tools are based on the n-tuple so permit analysis to be continued into PAW. There are two tools:-

ANL - The Event Analyser

This tool allows you to define your own n-tuples. These ntuples can contain data from the following structures:-

• The current event data structure.

• The persistent data structure e.g. the run header.

• Title (i.e. Database) banks.

You can create as many as you want simultaneously and can include simple cuts to select the events you wish to study.

TCA - Time Correlation Analyser

This tool allows you to look for time correlated events in a time-ordered n-tuple file (possibly created by ANL). Each time a correlation is found an entry is written to a new n-tuple. You present TCA with a request in a way that is essentially the same as for ANL. This request defines the cuts that determine what constitutes a correlation and also what to write to the output n-tuple when one is found.

There are chapters devoted to both of these tools.
