X-ray study of early type stars in the Carina OB1 association Antokhin I.I., Rauw G., Vreux J.-M., van der Hucht K.A., Brown J.C. <Astron. Astrophys. 477, 593 (2008)> =2008A&A...477..593A
Source_Number
A running source number in order of increasing J2000.0
Right Ascension, which uniquely identifies the X-ray source, but not the
entry in the table. Since this table contains all (557) X-ray detections of
235 sources for which the total logarithmic likelihood exceeds 10.0 in 5
separate overlapping XMM-Newton observations of this region, and many sources
were detected in more than one observation, the combination of source
number and data set number (data_set) uniquely specifies an entry in this
table.
Name
The name of the X-ray source using the '[ARV2008]' prefix (where
ARV2008 refers to Antokhin, Rauw, Vreux 2008), together with the X-ray source
number, as recommended by the CDS Dictionary of Nomenclature of Celestial
Objects.

The data set number, e.g., 1, or the numbers of the data sets
