Astronomical image data reduction pipeline

 THELI is a powerful tool to reduce optical, near- and mid-infrared
 astronomical imaging data, supporting more than 100 different single-
 and multi-chip instruments at professional observatories world-wide. The
 graphical user interface and internal data model allow the user to
 concentrate on the highly automated data processing, without being
 side-tracked by the specific complexities and characteristics of optical
 and infrared instruments. THELI is fully scalable on multi-processor
 machines with shared memory, allowing fast processing also of large data
 sets. The integrated data viewer allows access to any products on drive
 as well as in memory. User-defined instruments can be added, making
 THELI interesting for amateur astronomers as well.
