Table 1: Observational details. MTF $\equiv$ MTF-deconvolved, PD $\equiv$ phase-diversity restored. Pixel size 0 $.\!\!^{\prime\prime}$ 041. 1 $^{\prime \prime }$ = 734 km, 100 km = 0 $.\!\!^{\prime\prime}$ 14. The KAF4200 and KAF1600 CCDs from Eastman Kodak sit in Megaplus 4.2 and Megaplus 1.6 cameras, respectively.
