KAB magnitude distribution of the 3068 field galaxies identified in the sample. The steep drop-off after K ~ 19.3 is due to the criteria that σK ≤ 0.10 for each galaxy, and that is it detected in five other bands. This represents a decline in completeness of the sample. The typical 3σ limiting magnitude for an individual image as determined from the sky background is KAB ~ 20.4.
