Tom Barlow has written an automated data reduction tool for reducing 2-D echelle data such as produced by HIRES and ESI. This tool, called ``makee,'' allows the user to input the file names for the object, flat, wavelength cal., bias, and a brighter trace star. and outputs a partially reduced set of 1-D spectra, one for each order on the detector.

The MAKEE manual can be found here. The following contains some ESI-specific notes.

ESI wavelength calibration is typically done using three lamp sets: HgNe, XE, and CuAr. MAKEE can only accept two wavelength calibration files. You can take the HgNe and Xe spectra on the same image, since their intensities are fairly well-matched, or if you have the spectra in separate files, add the Xe image to the HgNe image.

Multiple objects can be handled by specifying the extraction window using "uop=". See the uop help file for details.
