We apply the UV/optical criteria BM/BX, BzK and IRAC Peakers to a sample of 24μ m selected galaxies from the COSMOS field with the goal of quantifying their contribution to the 8μ m rest-frame Luminosity Function (LF) at z˜2. We slightly modify the BM/BX and BzK criteria to adapt them to the COSMOS filters. 93% of the MIPS sources with 1.4 < z < 2.5 are properly selected as BzK and 68% of the MIPS sources with 1.5 < z < 3 are IRAC Peakers while only 50% of those with 1.5 < z < 2.8 are selected as BM/BX. The BzK criterion is independent of dust extinction while the BM/BX is highly affected by this phenomenon. We compute the 8μ m rest-frame LF for all the sources and we find the same proportions for the contribution of these different selections to the LF at z˜2.
