Previously published in Adams et al. (2013). Table columns are as follows: Col. 1: the HVC name of the source following the traditional convention of galactic coordinates at the nominal cloud center and the v_LSR of the cloud, for example HVC214.76+42.45+44 has l = 214.76°, b = 42.45, and v_LSR = 44 km s^-1; Col. 2: identification number in the Arecibo General Catalog (AGC), an internal database maintained by MH and RG. This identifier allows for easy cross–reference with the ALFALFA survey catalogs. Generally, we will use this identifier for the UCHVCs for brevity. Footnotes in this column indicate references for previously published UCHVCs; Col. 3: equatorial coordinates of the H i centroid, epoch J2000; Col. 4: recessional velocity in the heliocentric frame; Col. 5: H i line full width at half maximum with estimated measurement error in brackets; Col. 6: average angular diameter at the half-flux level, , computed as the geometric mean of the major and minor axes of the half-power ellipse: ; Col. 7: flux density integral in Jy km s^-1 with measurement error in brackets; Col. 8: log  of the H i mass for an assumed distance of 1 Mpc in units of M_⊙; Col. 9: log  of the representative column density, , in units of atoms cm^-2.
