Histogram of photometric redshifts for newly classified sources. 47 million (42%) have available photometric redshifts. We note the large portion of stars with large photometric redshifts, even when limiting to those with the most confident fits (error class = 1). The distribution of classification probabilities for these sources is not shifted towards lower values, and we suggest it is likely due to the photometric redshift pipeline incorrectly identifying galaxies as stars.
