Abstract: NICI, the new adaptive-optics supported Near Infrared Coronagraphic Imager of the Gemini Observatory (South), has recently been commissioned and offered to the astronomical community. We describe its reduction package and design of the different modules. The software has been written in Python using numerical routines from Numpy, Scipy and Ndimage, as well as the Gemini module Astrodata dealing with Gemini’s fits-file structure. We discuss science data preparation, and basic reduction steps as well as the implementation of the Angular and Spectral Differential Imaging (ADI/SDI) reduction algorithm, and the LOCI method (Locally Optimized Combination of Images) producing the final set of reduced science FITS files for high-contrast imaging.
