Ok, it's kind of clear why the problem appears. The actual data in the plot is normalized by a factor 100 as you can see from the colorbar. So when the raw data is exported, the normalization factor is not included (or rather, it is included but should not be). This is a bit tricky to solve perhaps because the export functionality is (as far as I know) a part of the plot (meaning, not a piece of code we wrote), but we can probably figure it out. Meanwhile, you'll just have to remember the normalization and apply it manually in whichever other plotting program you use.
