Photometric redshifts of galaxies in the HDF-S NIC3 field

The image shows some examples of photometric redshift determination for faint galaxies in the HDF-S NIC3 field. The filled points are the fluxes measured in the five colors observed with the VLT Test Camera (U, B, V, R and I) and in the infrared H spectral band with the NICMOS instrument on the Hubble Space Telescope. The curves constitute the best fit to the points obtained from a library of more than 400,000 synthetic spectra of galaxies at various redshifts.
