Comparison of best fit templates for each candidate cluster galaxy for a rich candidate cluster at zclus =0.35. The blue and red points respectively show the new templates considered as late-type galaxies (LTGs) and early-type galaxies (ETGs). The black squares show galaxies moving from ETG to LTG and vice versa. The old template is the best fit template in the original catalogue (the redshift is free to vary during the SED fitting), while the new template is the best fit template when we force the galaxy to be at the cluster redshift (zphot,gal = zclus). This illustrates that template fitting of galaxies is quite sensitive to small changes in redshift, but that classifications are relatively stable.
