Comparison of the BAO peak locations in spectroscopic (upper panel) and photometric (lower panel) redshift data. The vertical lines in various colors correspond to the location of the BAO peak found by fitting a six-parameter model to various μ bins. The vertical black line is the average and its error bar for all μ bins combined. There is a systematic shift that has to be accounted for by either a correction factor or dedicated templates for photometric redshifts.
