Cases 24-73 from auxiliary dataset: mitosis

I'm confuse. In the description of the auxiliary dataset (mitosis) is said that each case of the 24-73 is represented with one image region with area of 2 mm2. If the spatial resolution is 0.25 μm/pixel, the size of the image should be of 8000 x 8000 pixels. But this images have a size of 5657 x 5657 pixels. Do these images have different spatial resolution? or Do these images represent a region of 1.41 mm2?

You are forgetting to convert the units: 8000 x 8000 pixels = 2 mm x 2 mm = 4 mm^2. 5657 x 5657 pixels = 1.41 mm x 1.41 mm = 2 mm^2

Thank you. The confusion came from the description of the first 23 cases: "HPF, defined as 0.5×0.5 mm2 or 2000×2000 pixels", that is 0.25 mm2.

I don't see a problem with this description.
