k + e-corrections to z = 0 using different sets of templates. Top panel: k + e-corrections in the colour g − i used to determine the compatibility in colour ranges of the galaxy samples. The black curve corresponds to the templates used in this work by Wake et al. (2006) which are based on the stellar population synthesis code by Bruzual & Charlot (2003) using passive evolution. If a low level of continuous star formation is added to the model, the red solid line results. In addition we show the k + e-corrections from Banerji et al. (2010) using population synthesis models by Maraston et al. (2009) as the blue dotted curve. Bottom panel: k + e-corrections in the r band in which we compute galaxy luminosities. The coding of the curves is the same as above. The grey vertical lines indicate typical redshifts of the samples under consideration.
