This is a <i>SkyView</i> rendering of the HST ACS data as described in
the <a href="https://archive.stsci.edu/pub/hlsp/goods/v2/h_goods_v2.0_rdm.html">release
document</a>. This comprises four bands of observations of each both the north and south GOODS regions.
<p>
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.
<p>
The exposure times are given as:
<table>
<tr><th colspan=3> GOODS ACS exposure (s)</th></td></tr>
<tr><th>Band</th><th>North></th><th>South</th>
<tr><td>z850</td><td>24760</td><td>18232</td></tr>
