Comparison between the KLFs determined from the entire field (black line) and those from the worst field (red line), the best field (blue line), and NACO data (dashed line). The KLFs are computed after correcting the magnitude of each star using the extinction map of Dong et al. (2011) and applying Mask 3. The dotted straight line indicates the faintest magnitude down to which the counts can be assumed complete for all fields.
