NGC 2516 Chandra X-Ray Point Source Catalog

The authors have analyzed eight individual Chandra observations, comprising 5 ACIS and 3 HRC-I observations. They have combined these datasets to achieve the greatest sensitivity, reaching down to a threshold level of log f<sub>X</sub> = -14.56 (erg/s/cm<sup>2</sup>), or log L<sub>X</sub> = 28.69 (erg/s) at the 387 pc distance of NGC 2516.

Out of 284 X-ray sources detected, 155 are identified with photometric cluster members, with very little ambiguity, another 60 with non-members. There are 4 X-ray sources with two possible optical identifications (one cluster member and one nonmember for each), with no obvious choice between the two candidates. These 4 X-ray sources are listed in this Browse table twice, one for each optical counterpart, hence there are (284 + 4 =) 288 entries.
