| Description: The ACS Ultra Deep Field (UDF) is a cycle 12 survey carried out using the Advanced Camera for Surveys (ACS) on HST and taking advantage of the Director's Discretionary time. The UDF consists of a single ultra- deep field (412 orbits in total taken in 4 bands) within the CDF-S GOODS area. It is the deepest image ever obtained with Hubble. This service also includes data from the UDF follow-Up program by PI Massimo Stiavelli and colleagues obtained under HST cycle 14 program 10632 titled Searching for galaxies at z6.5 in the Hubble Ultra Deep Field (also known as UDF05). |
