The roughly constant star formation rate from redshifts 16 found in this study is consistent with the original results. Star formation rates from this study, Lyman break galaxies, and submillimeter observations are now in concordance. The spike of star formation at redshift 2 due to two ultraluminous IR galaxies in the small deep NICMOS field is smoothed out in the larger area results presented here. The larger source base of this study allows comparison with predictions from hierarchical galaxy formation models. In general, the observation are consistent with the predictions. The observed luminosity functions at redshifts 16 are presented for future comparisons with theoretical galaxy evolution calculations. Mid- and far-infrared properties of the sources are also calculated and compared with observations. A candidate for the VLA source VLA 3651+1221 is discussed. Description: Observations utilized in this study are all from the Hubble Space Telescope (HST) archives. The first set is the processed WFPC2 images of the NHDF produced by Williams et al. (1996, Cat. J/AJ/112/1335). The second set is the archival data from the NICMOS survey of the entire NHDF by Dickinson (2000, Phil. Trans. R. Soc. London A., 358, 2001). The NICMOS F110W and F160W data were reprocessed File Summary:
