Figure 2.1.0: Slews performed after FOS target acquisition (after guide star acquisition) to center the target in the science aperture. The average red side offset, based on 128 acquisitions, is: V2 = 0:0800 0:0500, V3 = -0:0500 0:0600. The average blue side offset, based on 148 acquisitions, is: V2 = 0:1500 0:0500, V3 = -0:0600 0:0500. Seventy percent of the pointings after guide star acquisitions are within 1" of the target.
