The first set of talks is intended to outline the "scientific landscape" relevant to possible ACS surveys, identifying the key issues that could or should be addressed with major surveys at high latitude. The main focus of the meeting is on "field surveys" as opposed to surveys pointed at particular objects. Nevertheless speakers are encouraged to put potential field surveys in context of other kinds of surveys likely to be carried out with ACS.
The second set of talks outlines current plans for ACS guaranteed-time and parallel observations, provides technical information on ACS, WFC3, and planning & scheduling.
The third set of talks, early Thursday afternoon, are intended to provide background information on existing or planned surveys from other facilities. Presenters are encouraged to focus on surveys relevant to ACS (i.e. ones with relatively small solid angles), and provide their views of what the most important scientific benefits would be from having ACS data to complement the data from other facilities.
