Bands included in the final OTELO multi-wavelength catalogue. From right to left: GALEX FUV and NUV, optical u, g, r, i, z from CFHTLS; J, H, K_s from WIRDS, I1, I2, I3, I4 corresponding to channels 1 to 4 of Spitzer/IRAC, and far-infrared 24 μm from Spitzer/MIPS, 100 μm & 160 μm from PEP/Herschel. The profiles of Herschel/SPIRE are not shown. As a reference, black dots represent limiting magnitude (3σ, ∼50% completeness) compiled from the literature or, in the worst case, measured directly in the corresponding field data. Green dots represent the limiting magnitude of HST-ACS606 and HST-ACS814 data, whose profiles are not represented here for the sake of clarity.
