• 03/09/2004 - The High Level Science Products were released on Tuesday, 09 March, 2004.


• Raw data - The primary ACS/WFC UDF raw data comprise approximately 0.5 terabytes and will be of interest mainly to those users looking for time-variable sources. Typical internet bandwidths will make electronic retrieval of these data slow for most users, and we will consider delivery using hard media such as DVDs. Those who intend to use the raw data should email the HST Archive.


• 10/31/2003 - UDF Coordinate list: Sign up to request a list of coordinates for the 100 reddest objects in the UDF field. A list of retrievals to date is also available.


• 08/27/2003 - In order to facilitate spectroscopic follow-ups from the ground, we are planning to pre-release (goal is October 30th) the coordinates of the 100 reddest sources. The expected depth of the data used for selecting these objects is about 30 per cent of the final depth.
