This is a SkyView rendering of the HST ACS data as described in
the release
document. This comprises four bands of observations of each both the north and south GOODS regions.
These data are stored in SkyView as a hierarchical image with 7 levels of pixels, each with a factor
of 2 change in scale. Thus the coarsest sampling using pixels 64 times larger than the finest. As we go to
coarser pixels, 4 adjacent pixels forming a square are averaged to create the pixel in the next level. The coarsest pixel
scale that is at least the resolution requested is used.
The exposure times are given as:
GOODS ACS exposure (s)
BandNorth>South

V60656505450
