Caption: Figure 6.
As in Figure 4, x and y residuals as a function of time for four parameter modeling of a sample of KIC-identified giants in Channels 41–44, but for 11 quarters. Top row, Quarters 3–6; middle row, Quarters 7–10; bottom row, Quarters 11–14. The top half of each box contains x residuals with y below. The y-axis range within each coordinate half-box is ±20 millipixels with an x-axis range between 80 and 90 days. The residuals exhibit time dependency within each quarter that correlates with focal plane temperature changes. Season 0 appears to have a larger fraction of stable astrometry.
