HDF-South K photometric redshift catalog

Using a combination of deep near-infrared (NIR) data obtained with the Infrared Spectrograph and Array Camera at the VLT and the WFPC2 Hubble Space Telescope data, we construct a K-band-selected sample which is 50% and 90% complete for K_s,AB_<=23.5 and K_s,AB_<=22.0, respectively, where the magnitudes are measured over a 2.0" diameter aperture.

For z<=3, our selection by the K-band flux chooses galaxies based on wavelengths redder than the rest-frame V band, and so selects them in a way that is less dependent on their current star formation rates than selection in the rest-frame UV.
