The cardinal positions (12, 3, 6, 9) have coordinates of 0 and 3.  The in-between positions (1, 2, 4, 5, 7, 8, 10, 11) have coordinates of 1.5 and 2.598076211...

     In the bottom half of the clock face, Y values are negative.  On the left half of the clock, the X values are negative.

     Rounding 2.598076211... to 2.6 for illustration, the X,Y coordinates look like the diagram.

(I'm using Misty's radius of three in this example)
