This is not intended to be a definitive tabulation of accepted Muon Collider parameters. It has been compiled using a variety of sources, and makes assumptions to obtain parameters that are not available or unknown to the author. Its object is to gain insight into the orders of magnitudes of our proposals, not an actual description. It arose from a request for a list of all the needed rf systems, but it goes a little beyond that, including some magnet specifications, but it is far from complete. Where there are multiple technology options, these will be mentioned and sometimes tabulated, but for the Summaries at the end, only one choice of technologies will be used. In some cases, parameters for a Neutrino Factory are also given for comparison.
