The description of Column 6 of Table 1 in Section 3.2 of our paper was based on a previous version of the catalog and does not apply to the published version of Table 1. The correct description of the H I column density, N_H I, that is presented in Table 1 is: the H I column density, N_H I, at the cloud center is 1.94 × 1018 T pkΔv cm-2 in the optically thin limit, an assumption that is reasonable because the emission is faint. An integrated intensity map was not used to subtract a background when determining N_H I, and was only used when determining θmaj, θmin, and M_H Id^{-2}. The background subtraction from the line profile in the determination of T pk was inherently included in the calculation of N_H I.
In Table 3, the 90% range of T pk was erroneously printed twice, once correctly representing the 90% range of T pk and once incorrectly representing the 90% range of N_H I. The correct 90% range of N_H I is (0.4-6.6) × 1019 cm-2 (instead of (0.2-2.2) × 1019 cm-2). All remaining values in the paper are correct however, including the median H I column density of 1.4 × 1019 cm-2. The corrected Table 3 is given below.
Neither of the above revisions affect the N_H I values in Tables 1 and 2, and they do not affect any of the conclusions of this work.
