I think this has to do with the calibration of the image.
If I run the macro on the flybrain image (in one duplicated slice, which is
calibrated in um) the new circle is centred elsewhere and it becomes larger.
If I remove the calibration, then it works fine.

So try adding "raw" to the values that you get, i.e.:

W1 = getValue("Width raw");
H1 = getValue("Height raw");
xb = getValue("BX raw");
yb = getValue("BY raw");
