DEPRACATED.  PLEASE SEE UPDATE

 

The chemical freeze-out temperature and baryon chemical potential used for the Cu system is from the code output below.  We have refit all the Au data as well which have been presented before.  However, we do not use the new values in the talk, rather the old values.  The refit results are slightly different, but consistent, because the yields have been refit to maintain congruence with the models and cuts used in the Cu+Cu 22.4 GeV analysis.  The actual errors are calculated by many such runs, as shown below, where we alternate the ratios by the error on each ratio.

 

Here is all the data with stat and sys errors on the ratios, a sample output from the code run, and plots from those fits are attached.
