The first column lists the source name. The next two columns give their J2000 equatorial coordinates. Columns (4) and (5) give their galactic coordinates. Columns (6) and (7) show the radial velocity of peak emission from the maser and molecular lines. Column (8) presents the peak flux density. Columns (9)-(11) present the distance from the Galactic center, and the far and near kinematic distances.
