making a grafh representing the isodensity values around the He dimer, the BCP point is just beyond the VdW limit (0.001 electrons). So, I have manually added a new contour line with a isodensity value of 0.0005. However, the number appearing in the graph seems to be rounded to three decimal places, appearing again 0.001. I'm sending you the image to see the problem. Thanks again for all your effort.
