Fig. 7
Fraction of measured flux in the CCD for strip 9, row 1 and FoV 2 in AF is plotted as a function of the centering offset with no AC motion (top) and maximal AC motion (bottom). For assumed maximal centering offsets of about one pixel the dependence on the colour V−I of the source is the dominating effect for AC flux loss with variations up to 1.1 percent.
