At the top is a set of two check boxes. The first is labeled "Set first end cell size:", and is followed by a text box to its right and the word "or". On the next line, the second check box is labeled "Check to pick size graphically". In this example figure, the first box is checked, and the text box contains the value .0001.

Next is a second set of two check boxes, the same as the first set, except that the first check box is labeled "Set last end cell size:". Again, the first box is checked, and the text box contains the value .0001.

At the bottom are two radio buttons, labeled "Cell sizes are fractional arc lengths" and "Cell sizes are absolute lengths", with the second button selected.
