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.
