Caption: Figure 12.

Top row: reduced frames of strip 0, with and without a Δm = 7, ρ = 0.″3 companion. Middle and bottom rows show residuals between strip 0 with a companion and the other strips. Since the companion is centered along a different azimuth, the residuals are strong enough to allow detection of a flux source that does not rotate with the instrument baseline. This detection is on the critical KS contour in Figure 11 and represents a marginal detection. The truncated grayscale is in detector counts.
