Software tools

The FOCES echelle data reduction software (EDRS) consist of a number of modules written in IDL. Such modules comprise the basic input/output and data-handling routines, display functions that allow inspection of the original and reduced data auxiliary routines which support detection of features and image processing, and echelle spectrum extraction. In addition to the basic modules there exist application comand files to extract well-calibrated one-dimensional spectra in a fully automatic mode. Since the language is interpreted, the FOCES software package consists of source code. All procedures or functions include a documentation header that can be read online with an INFO command.
