We analyze several thousand archival images from the NOAO Science Archive obtained over the last five years using the KPNO 4m Mayall and CTIO 4m Blanco MOSAIC cameras in order to determine the delivered image quality. We fit the resulting point spread functions with Moffat functions and find that the profiles are well approximated with beta approximately 3.5. We then analyze the DIQ distributions and investigate their dependence on various observational, environmental and temporal variables. We find that the DIQ of the MOSAIC cameras is similar at both sites.
