| xPos | nvssSource | NVSS | X position (RA direction) of the radio source | real | 4 | pixels | POS_CCD_X | |
| xscprox | allwise_sc2 | WISE | 2MASS Extended Source Catalog (XSC) proximity. This column gives the distance between the WISE source position and the position of a nearby 2MASS XSC source, if the separation is less than 1.1 times the Ks isophotal radius size of the XSC source. This identifies WISE sources that are identically the 2MASS XSC source as well as WISE sources that are fragments of large galaxies. This column is "null" if there is no 2MASS XSC source in proximity to the WISE source. If xscprox<2" and is not "null", the WISE source is assumed to be the galaxy detected by 2MASS. The WISE source is measured using an elliptical aperture with a size, shape and orientation that is scaled from that of the 2MASS XSC source. The elliptical aperture parameters and photometry are given in the w?rsemi, w?pa, w?ba, w?gmag and w?gerr columns. | float | 8 | arcsec | ||
