projections onto the ground. The results of these computations 
are shown on Figure 3. Shown here are the outlines of the 
detector arrays, subjected to the simultaneous roll, pitch and 
yaw of *0.1, -0.1 and 0.0 radian. 
Figure 4 shows the path on the ground traced by the nine detector 
arrays when the translation is applied simultaneously with the 
Euler rotations.
