Recovered SN Ia rate for the sample_psnid_zphot_best (the real observing case) with rate predictions of progenitor models from Greggio (2005). Error bars on the blue point are due to statistical uncertainties scaled to 10 yr over the simulated ∼15 deg² (although we expect higher statistics with the real survey, with statistical errors reduced by more than one order of magnitude). The gray points represent rate measurement from the literature, as shown in Fig. 1.
