Resumen
Using the UBVIJK photometry from the GOYA Survey of the Groth strip, we have built a catalog with photometric redshifts for 2000 sources (0 < z < 5). For z < 1.5, excellent agreement is found with spectroscopic redshifts (< dz/(1+z) >= 0.07). Such catalog will provide a robust determination of the evolution of the K-band luminosity function, as well as the galaxy mass function.
