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
