5. Farther down in the Properties window, click “Radius Tool” to open the Radius Tool
choices. Set the “Number of Decimal Places” to 3. Click “OK” to close the Proper-
ties window.
6. One at a time, drag the three circular handles on the Radius tool until they are all on
the k = 4 ring and the handles are about 120 degrees apart. The outer rings may par-
tially be off the screen. (Recall that the innermost ring is k = 0). Check the fit of the
circle to the ring with your eye. If k = 4 is not clear enough, start with k = 3.
7. NOTE: Because “Use Magnifier With Tools” was selected earlier, the image is mag-
nified when you click and hold the mouse on a point, such as one of the circular han-
dles. The default magnification is 2X, and the magnification can be adjusted using
the scroll-wheel on the mouse. The magnified image makes it easier to position the
Radius Tool circle on the specified ring of the triplets.
8. Record the value for the radius, R, to three decimal places in Table 1 below (where k is the ring number).
9. Move the X-Y Axes so the origin is at the point marking the center of the circle.
10. Using the same Radius Tool circle, repeat the measurement process for the k = 3, k = 2, k = 1, and k = 0 circles (if possi-
ble).
•
NOTE: Don't define a new Radius Tool since they would be on top of each other. All of the circles should have their cen-
ters at the same point.
For Run #1, Measure the Radius of the Triplets for B
and k = 1
11. Slide the playback slider back all the way to the right to show the image of the B
0 data for which each line has become
a triplet (and B is at its maximum value).
12. Adjust the Radius tool to measure the radius of the triplets of the k = 1 ring. Record the measurements in Table 2 below.
For the outer triplet ring, record the radius as R+. For the inner triplet ring, record the radius as R-.
