DNF โ Galaxy photometric redshift by Directional Neighbourhood Fitting
Wide field images taken in several photometric bands allow simultaneous measurement of redshifts for thousands of galaxies. A variety of algorithms to make this measurement have appeared in the last few years, the majority of which can be classified as either template or training based methods. Among the latter, nearest โฆ
