Miralles,Norbert Purger,Samuel Schmidt,Jack Singal +25 more
TL;DR: The PHoto-z Accuracy Testing Program (PHAT) as mentioned in this paper is an international initiative to test and compare different methods of photo-z estimation, and the test data sets are publicly available and can be used to compare new, upcoming methods to established ones and help in guiding future photoz method development.
