Paper Abstract

This paper describes the echelle reduction package available within MIDAS, the ESO image processing system which runs on VAX computers. The reduction method is currently used to process spectra from the echelle spectrograph at the Cassegrain focus of the ESO 3.6 m telescope at La Silla, Chile. The package is very modular, with intermediate data structures allowing the communication between the different reductions steps. As a consequence, the reduction method is flexible and can be adapted to a wide variety of instrumental configurations. The basic reduction steps: wavelength calibration, data extraction, and flux calibration are performed with minimal user interaction. Some results showing the accuracy of the method are presented.
