Results of the mock analysis for the SED modeling using the nonparametric SFH model. The input parameters we used to build the mock catalog are shown on the x-axis, and the results from fitting the mock catalogs are shown on the y-axis. From left to right, the upper panels present the instantaneous SFR, the stellar mass M_*, and the IR luminosity L_IR. The middle panels present the time-averaged SFRs for the last 100, 150, and 270 Myr over the SFH, and the bottom panels present the time-averaged SFRs for the last 270 and 500 Myr over the SFH as well as the SFR gradient computed over the last 300 Myr. The one-to-one relation is indicated by the solid black lines. The bias and precision estimated for the parameters are indicated in each panel.
