Our analysis proves that photometric redshift techniques can and must be used to extend the range of applicability of the spectroscopic redshift measurements. Open access • Journal Article • DOI We show that the redshift distribution of our sample is in excellent agreement with smaller and much deeper photometric and spectroscopic redshift surveys.

Taylor - Show less +10 more If such better models are available, the clustering-redshift technique promises to be a highly complementary alternative to other methods of redshift calibration. Open access • Journal Article • DOI We present a simple and powerful empirical method to constrain photometric redshift uncertainties in the absence of spectroscopic redshifts. Hence, the redshift can be determined during the growth process. Open access • Journal Article • DOI Nikhil Padmanabhan , Tamás Budavári , David J. Schlegel , Terry J.

Open access • Journal Article • DOI These results have strong implications for the analysis of redshift surveys at intermediate redshift.
