Final stacked soft-band images (all smoothed with a Gaussian of FWHM = 3 pixels for illustration purposes) used for further analysis: a) ref-lowZ (P = 0.999), b) BZ-UV (P = 0.993), c) Spec-U1 (P = 0.999), d) Spec-U2 (P = 0.958), e) Spec-B1 (P = 0.974), f) Spec-B2 (P = 0.560). The white circles indicate the 5 pixels diameter apertures used for flux extraction.
