More Reconstruction Binning

Below shows the evolution the reconstruction of binning on a run with 200,000 photometric and spectroscopic objects with 20 spectroscopic redshift bins. The number after "reconstruction" in the legend is the number of reconstruction bins. The best reconstruction is with 40 bins which is again 2X the number of spectroscopic redshift bins. I am running another run with more redshift bins to see how that effects things. I am going to look deeper into the reconstruction code to see if there is something hard-wired in that Alexia forgot to tell me about. Some reason why it only reconstructs well with 2X the redshift bins.

Looking at binning close up around the best fit (40). You can see that even around the best fit the reconstruction behavior is erratic:
