We present a description of the CL-based package XDSpres, which aims at being a complete reducing facility for cross-dispersed spectra taken with the Ohio State Infrared Imager/Spectrometer, as installed at the SOAR telescope. This instrument provides spectra in the range between 1.2 μm and 2.35 μm in a single exposure, with resolving power of R ∼ 1200. XDSpres consists of two tasks: namely, xdflat and doosiris. The former is a completely automated code for preparing normalized flat-field images from raw flat-field exposures. Doosiris was designed to be a complete reduction pipeline, requiring a minimum of user interaction. General steps toward a fully reduced spectrum are explained, as well as the approach adopted by our code. The software is available to the community online.
