Introduction

The Data Display Tool is a collection of libraries and tools for the transfer, display and manipulation of data coming from instrument and telescope detectors. The DDT is a product that is being developed in the scope of an outsourcing contract by the company CGI. The IFW v5 is packing a snapshot of the actual version.

Warning

Disclaimer:

ESO does not ensure the correct functioning of the DDT Viewer or libraries contained in version 5 of the ICS Framework. This version of DDT and its documentation is delivered “as is” without warranty of any kind.

We have enhanced several graphical capabilities in the DDT Viewer since the last version. However, due to some contractual constraints, we are unable to provide the updated documentation within this version.
