This manual is specific to the procedure of reducing galaxy long-slit spectroscopic data from the Boller and Chivens Spectrograph aboard the 90 inch Bok telescope at Kitt Peak National Observatory. The Image Reduction Analysis Facility (IRAF) is utilized to complete the steps of image reduction. This manual will discuss methods of removing instrumental signatures, correcting for radiation events from environmental conditions, and the data frames for wavelength calibration for the particular data presented. As a result, the reduced and calibrated image with a zoomed-in figure will present the h-alpha emission line and continuum of a galaxy.
