Diffusion-correction code developed by Sigfus Johnsen,University of Copenhagen. which uses Maximum EntropyMethods (MEM) to invert an observed power density spectrum. Code provided in 2011 by Bo M. Vinther, University of Copenhagen. Code adapted in 2012 by Tyler R. Jones, University of Colorado to include extrema picking. Used in the following manuscript to reconstruct seasonal isotopic-variability (maximum summer and minimum winter values) in the WAIS Divide ice core. Jones, T. R., Cuffey, K. M., Roberts, W. H.
