The catalog includes 388 X-ray-detected sources identified with the very deep XMM-Newton observations available for an area of 0.2deg2. The source detection was performed on the Rc-, z'-, and B-band images and the available photometry is spanning from the far-ultraviolet to the mid-infrared, reaching in the best-case scenario 21 bands. Astrometry corrections and photometric cross-calibrations over the entire data set allowed the computation of accurate photometric redshifts. Special treatment is undertaken for the X-ray sources, the majority of which are active galactic nuclei (AGNs). For normal galaxies, comparing the photometric redshifts to the 253 available spectroscopic redshifts, we achieve an accuracy of σΔz/(1+z)=0.036, with 12.6% outliers. For the X-ray-detected sources, compared to 115 spectroscopic redshifts, the accuracy is σΔz/(1+z)=0.069, with 18.3% outliers, where the outliers are defined as sources with |zphot-zspec|>0.15x(1+zspec). Description: The field has been observed with XMM-Newton in the time period between 2000 April and 2002 December. In the far-ultraviolet (FUV) and the near-ultraviolet (NUV) the Lockman Hole area was observed by the Galaxy Evolution Explorer (GALEX). Here, we consider the magnitude in 3" diameter aperture available in the General Release 4/5 (GR4/5). In the optical wavelengths, our data set consists of a compilation of observations from Large Binocular Telescope (LBT; between 2007 February and 2009 March in 5 bands (U, B, V, Y, and z')), Subaru (between 2001 November and 2002 April in the Rc, Ic, and z' filters), and Sloan Digital Sky Survey (SDSS-DR7). The near-infrared view of our sources is provided by the data release 7 of the UKIRT Infrared Deep Sky Survey (UKIDSS). For the near- to mid-infrared wavelengths we are using observations at 3.6um, 4.5um, 5.8um, and 8.0um from the IRAC. File Summary:

Note (1): LBT = Large Binocular Telescope. Aperture photometry corrected to total (only for GALEX and IRAC photometry) for point-like sources. Note (2): Detection flag as follows: 1 = Rc detection (5σ); 2 = z' detection (5σ); 3 = B detection (5σ); 4 = Rc detection (3σ), 5 = z' detection (3σ); 6 = B detection (3σ). Note (3): Complementary to the flag provided by SExtractor indicating saturation, we masked problematic regions on the images which include bad pixels and problematic areas close to stars, using 'Weight Watcher' (Marmo & Bertin, 2008ASPC..394..619M). For more details, refer to the associated description file of the catalog. Photometry flag as follows: -99 = 99 value produced by SExtractor either for the magnitude or the error, or source outside of the field -5 = Flag in the UKIDSS catalog marking noise in the JHK bands -4 = Saturation or incomplete/corrupted data produced by SExtractor -3 = Source inside a stripe, as marked by optical inspection of the images -2 = Magnitude error was negative -1 = Magnitude error was greater than 1 0 = Everything is OK 1 = FWHM in the detection band is zero 2 = Source inside wings of stars, potentially fake 3 = Magnitude greater than the detection limit Note (4): We use only the high quality spectroscopic redshifts from the original catalogs according to Table 4. Note (5): Sources with |Zvar,k±δZvar,k|>0.2 carry a flag 1, while the rest carry a flag 0. Note (6): Sources detected in the X-rays are flagged as 1, sources inside the XMM area without X-ray detection are flagged as 0, while sources outside the XMM area are flagged as -99. Note (7): The sources identified as X-ray counterparts will have the corresponding X-ray ID number from the XMM catalog (Brunner et al. 2008, Cat. J/A+A/479/283, <[BCH2008] NNNN> for Simbad). Note (8): As discussed in detail in Section 3.2.3, this column gives the merged morphology classification information from the HST and ground based images, provided only for the counterparts of the X-ray sources. Morphology code as follows: -2 = too faint; -1 = photometry blended with nearby source; 0 = extended source; 1 = point-like source.
