This value should be representative of the faintest stars clearly visible in the image. The brighter of the limiting magnitude estimates for the two second-epoch images is reported here.

This value should be representative of the faintest stars clearly visible in the image. The brighter of the limiting magnitude estimates for the two second-epoch images is reported here. The second estimate is the 80th percentile of the magnitude distribution of stars detected on all four images.
