Upper panel: k-correction to 1600 Å for the MegaCam riz filters, as a function of redshift based on the 100 Myr old continuously star-forming template with a dust attenuation of E(B − V) = 0.25. The average redshifts from the simulations and their uncertainties are represented by horizontal error bars. This leads to a corresponding error in the k-correction. Lower panel: shifts from apparent magnitudes in the MegaCam riz filters, to absolute magnitudes at 1600 Å. The Distance Modulus and k-correction are taken into account. The uncertainties in the average redshifts of the samples lead to uncertainties in the absolute magnitudes.
