\caption{Grades assigned to the DPS stacked images as a function of
the passband. The table gives: in Col.~1 the
passband; in Col.~2 the ESO filter number; in Col.~3
the total number of stacked images for each passband; in Cols.~4--7
the ratio of images with a given grade to the total number of images
taken with that filter.}
