Notes. Ages at which the sensitivity to ℓλ,IMF(t∗) reaches a x% value of the total sensitivity, tλ,x%, for 99, 95, 90, 80, and 50% and all luminosities used in this work. The last column is the Cλ value as defined in Eq. (8). The units of Cλ are in erg s-1 Å-1
yr for the standard photometric systems and photons s-1 yr for Q(H). Values in parenthesis correspond to the use of upper and lower envelope of ℓλ,IMF(t∗) obtained from our calibration of SSP models.
