I've looked at a few archived foton files to see if this caused any significant changes in any coefficients. Mostly what I've found are changes in the order of header information, but H1HPIBS.txt show a bunch of changes, all at the ~10^-6 level , so probably still harmless. Also, these changes are likely the result of a known (and now resolved) issue with quacking foton files with Matlab.
