  This manuscript describes the design, usage, and data-reduction pipeline
developed for the Magellan Inamori Kyocera Echelle (MIKE) spectrometer used
with the Magellan telescope at the Las Campanas Observatory. We summarize the
basic characteristics of the instrument and discuss observational procedures
recommended for calibrating the standard data products. We detail the design
and implementation of an IDL based data-reduction pipeline for MIKE data (since
generalized to other echelle spectrometers, e.g. Keck/HIRES, VLT/UVES). This
includes novel techniques for flat-fielding, wavelength calibration, and the
extraction of echelle spectroscopy. Sufficient detail is provided in this
manuscript to enable inexperienced observers to understand the strengths and
weaknesses of the instrument and software package and an assessment of the
related systematics.
