I want to stress that there is nothing wrong with the results in the paper. The mistakes are typographical in the sense that the formulas in the methods were transcribed incorrectly from our code. This was just pointed out to me that the errata could be misinterpreted. What happened was that MS Word kept turning our equations into pictures so we couldn’t edit them so we retyped them over and over again. Transcription errors then started to creep in and we were so adapted to the equations that we didn’t notice anymore. Not a good excuse but unfortunately that is what happened.
