Mathematical datum for Nereid

The following results are not based on any evidence, but are here to illustrate what I feel are best fit values for Nereid. My findings are based upon correcting uncertainties from reference values I have acquired from the internet and books.I have created a hierarchy starting at the top of the list with globally accepted values, where uncertainty in the value is the least, from a series of sampled results. The parameters lower down the list have a much greater uncertainty or are estimated by computation using my Nereid comparator program.
