Abstract

The new ESO Thermal Infrared Multi-Mode Instrument TIMMI2 is described in detail in Reimann et al. The TNT Timmi Navigator Terminal is the graphical user interface for TIMMI2. It provides the communication between telescope, instrument and reduction pipeline. The TNT in a very easy way allows the astronomer to prepare and run complex observing programs. The graphical elements are based on Forms Library (A Graphical User Interface Toolkit for X). The TNT is written in C. To facilitate the data analysis and administration, a dedicated reduction pipeline will be used. It is embedded in the MIDAS environment and runs in the background (except for tasks visualizing the progress and status of the reduction). The main components are a pre-processor which operates on individual images (e.g. for image cosmetics) and two post-processors which combine images (e.g. from nod-cycles) and allow further specialized reduction (e.g. for deriving of Stokes parameters from imaging polarimetry). The pipeline also stores and compresses the data for further (re)processing. The reduction steps are controlled by image header keywords and parameter files which can be modified via the TNT. The pipeline can run during the actual observations (on-line reduction with quality control) or during a stand-alone MIDAS session.
