Fig. 2. Restframe 8µm LFs based on the AKARI NEP wide field. The blue diamonds, the purple triangles, the red squares, and the orange crosses show the 8µm LFs at 0.28 < z < 0.47,0.65< z < 0.90,1.09< z < 1.41, and 1.78 < z < 2.22, respectively. AKARI’s MIR filters can observe restframe 8µm at these redshifts in a corresponding filter. Error bars are estimated from the Monte Carlo simulations (§3). The dotted lines show analytic fits with a double-power law. The smaller data points at the faint ends are adopted from the NEP deep field, where AKARI data are deeper (Goto et al. 2015), and are included in the fit. Vertical arrows show the 8µm luminosity corresponding to the flux limit at the central redshift in each redshift bin. Overplotted LFs are Babbedge et al. (2006) in the pink dash-dotted lines, Caputi et al. (2007) in the cyan dash-dotted lines, Huang et al. (2007) in the dark-yellow dash-dotted lines, Fu et al. (2010), in the dark green dashdotted line, and Kim et al. (2015) in the bright green dash-dotted line. Best-fit parameters are presented in Table 1.
