XMM-Newton observations of Extremely Red Objects and the link with luminous, X-ray obscured quasars. Brusa M., Comastri A., Daddi E., Pozzetti L., Zamorani G., Vignali C., Cimatti A., Fiore F., Mignoli M., Ciliegi P., Rottgering H.J.A. <Astron. Astrophys. 432, 69 (2005)> =2005A&A...432...69B
ADC_Keywords: X-ray sources ; Infrared sources ; Photometry Keywords: X-rays: surveys - galaxies: active - galaxies: Extremely Red Objects Abstract: We present the results of a deep (about 80ks) XMM-Newton survey of the largest sample of near-infrared selected Extremely Red Objects (R-K>5) available to date to Ks≲19.2. Description: These 2 tables contains the X-ray and optical informations of the sources detected in a 80ks observations of a sample of Extremely Red Objects. The X-ray hardness ratio (HR) and the optical to near-infrared color (R and K magnitudes) are reported for all the sources, along with the reliability of the X-ray to optical or near infrared association (likelihood ratio, LR(R) and LR(K)).

Note (1): The Table is splitted in 4 parts as follows: 1 = sources with secure X-ray to optical associations 2 = sources with ambiguous X-ray to optical associations 3 = sources with low X-ray to optical likelihood ratio 4 = sources without optical/near infrared counterparts
