BPZ is integrated with ColorPro, robust photometry across images of various PSF.  Robust photo-z require robust photometry!

BPZ has been widely used, but citations may include the following:

  • Benitez00 BPZ presented; HDF-N analysis
  • Benitez04 SED templates recalibrated; "Tadpole" & "Mice" analyses
  • Coe06 Two bluer templates added; UDF analysis (pretty pictures and results)

    • Example of a very good SED fit (with correct photo-z) to extensive and well-calibrated multiband photometry (from Coe10):
