Thank you for the example file.
I could reproduce exactly the behavior you reported.
I noticed that the values are mostly the same, except for some differences:
- The old function (AEC) return positive/negative values, while the new function (HENV) returns strictly positive values
- A small number of values are very different (not only a sign difference), like the one selected in the screen captures below (same as yours, but with the colormap configured with the option "Absolute values")
Old function (AEC):
New function (HENV):
