[53.09] A Survey with the HST

The Hubble Space Telescope has been used to observe a strip of 28 overlapping WFPC-2 fields. All fields but one are observed for a total of 2800 seconds with F606W (V) and 4400 seconds with F814W (I). The estimated limiting magnitude is $\sim27.5$ to $28$. One field (the ``deep'' field) has a total exposure of 25200 seconds in V and 26000 seconds in I.

In this poster, we present the data and a progress report. The science to be done with these data includes study of the number magnitude relation, angular size distributions, morphology, and clustering. All of these are affected by the cosmological model and scenarios for galaxy and cluster formation which are the scientific questions we will eventually address.
