Abstract: The Deep Extra-galactic Imaging Multi-Object Spectrograph (DEIMOS) under construction for Keck II will employ a detector comprised of a mosaic of eight CCDs. World coordinate system (WCS) information is needed for mapping between FITS pixels and many other systems. To permit an arbitrary number of WCS mappings, we extend the FITS metaphor by placing the WCS information in a FITS table. For the purposes of simulation and planning, the scheme can be generalized to accommodate mappings between non-FITS coordinates.
