From the constrained HOD model, the average mass of halos hosting the [OII] emitters is derived to be $\log{M_{eff}/(h^{-1}M_\odot)}=12. 70^{+0. 09}_{-0. 07}$ and $12. 61^{+0. 09}_{-0. 05}$ at z=1. 19 and 1. 47, respectively, which will become halos with the present-day mass, $M\sim 1. 5 \times 10^{13}h^{-1}M_\odot$.
