QVB: The QM Validation Browser

Introduction

This software was the basis of the CSDS supplied software CVB for viewing and validating Cluster CDF files by the PI teams.The official CSDS product should be fetched as part of the Cluster User Interface from the official CSDS site. This page is maintained for historical purposes and for non-PI users who may wish to use the cdf browsing side of the software. It is no longer actively maintained.

QVB is an IDL package which enables a user to browse and display CDF data files as used within the Cluster Science Data System and other potential projects. QVB is supplied as an IDL save set and/or source and runs as a standalone environment. It is written by QMW staff as part of our role in the Cluster Science Centre within the UK. The Particle Physics and Astronomy Research Council funds this project for the express support of the UK Cluster community, and authorized supply is therefore limited. The software includes a copyright notice and disclaimer. Users are free to modify their own private copies of the software, but should keep the original QMW Copyright notice/disclaimer as part of any modified copy.

• 2. MSWindows compatibility.
• 3. Plot of datafiles with multiple timelines (WIND MFI).

• Development of QVB for Cluster Validation has been transferred to JSOC at RAL under the acronym CVB as part of the Cluster Data Management System. Steve Guest (S.Guest@rl.ac.uk) might give you more information on CVB. CVB is essentially build on QVB version 4.2.
• QVB will meanwhile be maintained as a separate CDF-viewer though use of the Validation GUI is no longer maintained.
