A running sequential identification number for each source in the catalog in order of increasing value of the SIX parameter.
The unique 2MASS source identifier (Cntr).
The Right Ascension of the 2MASS source in the selected equinox. This was given in J2000.0 equatorial coordinates to a precision of 0.01 seconds of time.
The Declination of the 2MASS source in the selected equinox. This was given in J2000.0 equatorial coordinates to a precision of 0.1 aecseconds.
The Galactic Longitude of the 2MASS source.
The Galactic Latitude of the 2MASS source.
The 2MASS J Band Magnitude of the source.
The SIX figure of merit parameterization for the source, where SIX = log10 (SI + 0.116* SX), where S_I is the infrared color discriminator (1.7 * c2 + 2.0 * c3 + c4) and SX is the discriminator based on the distance d between the WISE and RASS source positions (d/e)2. The construction of S_IX is discussed in Section 2 of the reference paper.
The infrared color discriminator SI = 1.7 * c2 + 2.0 * c3 + c4, where the weights c2, c3 and c4 are defined by equations (2), (3) and (1) of the reference paper. See Section 2 of the reference paper for more details.
The logarithm of SX, the discriminator based on the distance d between the WISE and RASS source positions in multiples of the RASS positional uncertainty e, viz. SX = (d/e)2.
The RASS source name.
The VCV Catalog identifier of the source.
The AGN type as listed in the VCV Catalog.
The AGN redshift as listed in the VCV Catalog.
This flag parameter has possible non-blank values of:
1 = previously unidentified,i.e., not listed in the VCV Catalog; 2 = the source listed in the VCV Catalog does not fit this paper's definition of an AGN.
The HEASARC Browse object classification of the object, based on the veron_object_type parameter value. Note that the HEASARC has set all sources lacking a VCV object type to the generic AGN class, based on the authors' estimate that >~ 95% of sources in this table are AGN. This of course implies that <~ 5% (<~ 216 sources) are not AGN.
