CPz_S data set projected using SLMDS cross-matched with the GZ1 classifications. The top left plot shows the redshift of the galaxies in GZ1. The classifications (i.e., top right, bottom left, and bottom right plots) are color coded by the debiased vote fractions of the spiral (p_sp), elliptical (p_el), and otherwise (i.e., star, merger, or unknown) (p_x) categories following from the debiasing technique of Bamford et al. (2009). For reliable debiasing of the classifications, the redshift should be in the range 0.001–0.25 (Lintott et al. 2011).
