Abstract: DEIMOS (the DEep Imaging Multi-Object Spectrograph) began producing scientific data from the Keck II telescope in 2002 June. The instrument is extremely configurable, and the form of the output data is highly variable. Filters and gratings may be swapped, gratings and mirrors tilt, readout modes and active amplifiers of the 8-CCD mosaic change, and numerous field-specific astrometric slitmasks may be inserted. For archival purposes and to enable fully-automated data reduction, FITS files from DEIMOS document the instrument state, all aspects of the slitmask design, and multiple world coordinate systems for the mosaic images. The FITS files are compatible with existing local conventions for mosaic image display systems and also with incipient FITS WCS standards.
