Scientific paper

We have recently obtained ACS data of the NICMOS parallel field in the original Hubble Ultra Deep Field to detect objects at z=7 and 8. Catalogs were created with SExtractor using methods similar to those used for the original UDF. We will discuss the simulations we preformed to investigate the contamination of our catalogs of both the ACS and NICMOS data. Both model simulations and model-independent simulations were carried out to explore contamination from photometric errors on magnitudes and colors, completeness, crowding, and galaxy sizes and shapes.
