PLOS ONE PAPER sub pixel resolution

code and software needed to re-produce results in paper titled "Sub pixel resolution using spectral-spatial encoding in x-ray imaging" by Tim Szczykutowicz, Sean Rose, and Alex Kitt. we used some software from (referenced in code) Siewerdsen J, Waese A, Moseley D, Richard S, Jaffray D. Spektr: A computational 461 tool for x-ray spectral analysis and imaging system optimization. Medical physics. 462 2004;31(11):3057{3067. Hernandez AM, Boone JM. Tungsten anode spectral model using interpolating 466 cubic splines: unfiltered x-ray spectra from 20 kV to 640 kV. Medical physics. 467 2014;41(4):042101.
