Basic syntax for either HIRES or ESI data reductions:
makee    (object file)   (star file)   (flat file)   [ ccd= ]   [ arc file ]    [ bias=(bias file) ]
See complete syntax from 'makee -help' .
There are three required parameters to "makee":
For the HIRES 3 CCD system (2004 and later) you will also need to specify a CCD number-- 1, 2, or 3 for the blue, green, and red CCDs. (MAKEE reduces one CCD per run.)
If you want a wavelength calibrated spectrum you must also specify:
You can also specify a short dark (or bias frame) using the "bias=" option, although it is not required.
For HIRES, all these FITS files must have (nearly) the same echelle angle and cross disperser angle (except for the short dark image), within a tolerance of 0.02 units (note) .
For ESI, all the FITS files should have the same slit width, however this is not required. It is probably most important to match the slit widths of the object and flat field, different widths for the trace star and arc lamp should not have a significant effect.
