On the realistic validation of photometric redshifts, or why Teddy will never be Happy

1 code implementation • 30 Jan 2017 • R. Beck, C. -A. Lin, E. E. O. Ishida, F. Gieseke, R. S. de Souza, M. V. Costa-Duarte, M. W. Hattab, A. Krone-Martins

Two of the main problems encountered in the development and accurate validation of photometric redshift (photo-z) techniques are the lack of spectroscopic coverage in feature space (e. g. colours and magnitudes) and the mismatch between photometric error distributions associated with the spectroscopic and photometric samples.
