χ2 obtained by fitting the mock catalogs with CIGALE. The different fits for each simulated catalog are color-coded by σrun used in the fit. A high level of burstiness (σrun ∼ 0.8) provides good fit quality, whatever the intrinsic level of burstiness of the fitted galaxy, while smoother SFHs struggle to fit bursty galaxy SEDs.
