For information about this work, you should start with the paper itself.  As discussed in the paper, a key part of this project was exploring different possible w(a) grids.  The grid used for the results presented in the paper is the Zmax=4, linear in a grid (first on the list below).  It was chosen to maximize the FoM's for reasons discussed in the paper.

This archive includes eigenmode/value plots (like Figs 1&2) for every single data model and every single grid.  These can be useful for understanding which functions w(a) a given data model measures best, and also for better understanding the choices we made for the paper.  The figures are organized according to w(a) grid (labeled in bold face).  Under each w(a) grid heading are links to files containing the eigenmode plots, grouped according to the corresponding DETF figures.  Near the end of each list is a file with the corresponding DETF FoM bar plot (similar to Fig 3 in the paper). 

ASCII: The last link on each list is to a folder that contains ASCII files with the same information in numerical form.  The file names and comments in the files should be self explanatory. The large number of digits recorded in these files is an ad hoc choice made to preserve orthogonality of the eigenvectors and does not have physical significance.   Files named "aGrid..." in each folder give the a values that define the segments on which w is constant.

Additional notes:

<> The various codes in the figure labels and file names (such as S43T4430) just encode the same information I've also provided in words. "Ngrid" on these pages corresponds to "N_G" in the paper.

<> The figures are also available in PowerPoint format.  From there, individual figures can be cut and pasted into other files and applications for use in presentations and documents.  To find the PPT file, open the corresponding pdf file in your browser and then replace ".pdf" with ".ppt" in address bar.   (There are no separate links to the .ppt files.)

The next plots address the following question: 

Was anything missed by keeping Ngrid constant as we went from Zmax=4 to Zmax=7 or from Zmax=2 to Zmax=4?  For example, did the benefits of reaching to higher z get offset by the dilution of grid points at nearby z?

Answer: We have not found any significant discrepancies between high and low Ngrid with the same Zmax..
