The ESO-MIDAS (European Southern Observatory Munich Image Data Analysis System) system provides general tools for image processing and data reduction with emphasis on astronomical applications including imaging and special reduction packages for ESO instrumentation at La Silla. In addition it contains applications packages for stellar and surface photometry, image sharpening and decomposition, statistics and various others.

In addition to the application programs the ESO-MIDAS system further contains:

  • a powerful command language (MCL, MIDAS Control Language), that make it possible to create procedures;
  • the program interface, i.e. a set of subroutines/functions which is used by the application programs to interface hardware, or data

ESO-MIDAS is written by the MIDAS Group of the European Southern Observatory (ESO) in Garching bei Munchen, Germany.

ESO-MIDAS is available on the special ESO-MIDAS CD-ROM and also included on the Linux for Astronomy CD-ROM
