Data Monitor Tool Project

The Data Monitor Tool (DMT) project is a part of the LIGO Global Diagnostics System (GDS) and will define the tools and environments necessary to support continuous data monitoring of the LIGO interferometers.

Overview
Observatory hardware configuration
System Software

Interactive (Foreground) Environment

Setting up the User Environment.
Interactive running is based on the ROOT , a C++ interpreter with a class library useful for scientific data analysis. There is some introductory material for beginning users with a primary focus on High Energy Physics analysis.
The Sandbox library contains C++ classes and functions (ROOT Macros) which support interactive monitoring and fault diagnosis. It includes an online data interface and signal processing functions.
A Software Distribution Kit containing the Sandbox software and useful utility functions may be downloaded from this site.
Examples of ROOT sessions using the Sandbox.

Background Environments

Framework classes are defined.
The DMT library has classes to manipulate parameters, generate triggers, etc.

Many Background Monitors and Utility programs have been written.
A Data Simulation facility is also available

The dmt-discuss mailing list is used to distribute news from DMT-Land. The mailman web interface allows you to join the list or to view archived posts.
