September 26, 2000 A newly prepared Data Reduction Guide can be found at http://www.apo.nmsu.edu/Instruments/echelle/ARCES_data_guide.pdf. The Guide documents one well-tested procedure for advantageously reducing spectra obtained with the ARC echelle spectrograph. The procedure described utilizes tasks found within IRAF and includes some useful, "non-standard" steps. Questions or comments about the Guide should be directed to Julie Thorburn, at thorburn@yerkes.uchicago.edu.
