    Abstract

    The data reduction software for the Gemini High Resolution Optical SpecTrograph (GHOST) presents a number of unusual challenges. Star light from one or two objects and simultaneous sky is collected in integral field units rather than a slit or well-separated fibers. When used with binning, individual fibers are not resolved, and the optimal pixel weighting is derived from a simultaneous slit viewing camera. We describe the data reduction approach taken, including testing using an optical physics-based data simulator, and an object-oriented and modular approach to spectral extraction that fits within the Gemini recipe system, DRAGONS, using AstroConda.
