Description


This is a <i>SkyView</i> rendering of the HST ACS data as described in the <a href=http://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> <tr><td>i775</td><td>8530</td><td>7028</td></tr> <tr><td>V606</td><td>5650</td><td>5450</td></tr> <tr><td>B435</td><tr>7200</td><td>7200</td></tr> </table>
