The evolution of galaxies across the cosmic time are observationally studied by means of extragalactic surveys that cover significant volumes of Universe, with a wealth of multi-wavelength ancillary data. OTELO survey provides the deepest narrow band survey to date, in terms of minimum detectable flux, and emission line equivalent width, that has allowed detecting the faintest extragalactic emission line systems. In this way, OTELO data complements other broad band, narrow band, and spectroscopic surveys. The data has been obtained using the red Tunable Filter of the OSIRIS instrument at the 10.4 m telescope GTC, pointing at the most deeply explored EGS region. This catalogue is complemented with public data ranging from deep X-ray to FIR, including high resolution HST images, that allowed deriving precise photometric redshifts, and obtaining the morphological classification of the extragalactic objects detected. In the present contribution the final catalogue and other value-added products, that will be publicly available by mid 2019, are presented. The improved reduction techniques, the high astrometric and photometric quality achieved, and the main survey demographics are also presented. A total of 11 237 raw sources have been detected in a sky area of 56 sq.-arcmin. Within them, about 1 800 are fair candidates to the strongest emission lines in the UV-optical domain, 81 are candidates to stars, while other 483 are candidates to be absorption line systems. The 50% completeness of OTELO catalogue is obtained at an AB magnitude of 26.38. Photometric redshifts have been derived with an accuracy better than \vertΔz\vert/(1+z) ≤ 0.2 for 6 600 sources.
