Abstract

Column (28) in Table 1 was mislabeled. The observed H I line profile parameter W20, the line width at 20% of peak intensity, is related to the derived parameter WiR, defined by Tully & Fouqué (ApJS, 58, 67 [1985]) to agree statistically with twice the maximum rotation velocity:W2R=W220+W2t-2W20Wt[1-exp-(W20/Wc)2]-2W2texp-(W20/Wc)2 and for the rectification from viewing angle, i, to edge on:WiR=WR/sini, where Wt=38 km s-1 describes profile broadening by random motions, and Wc=120 km s-1 characterizes the transition from horned to Gaussian profiles.

The data in column (28) in Table 1 are incorrectly identified as representing WiR, the derived parameter. In fact, the data in this column are values of W20, the observed parameter. In the electronic edition of Table 1, the data within the table are unchanged, but the metadata description of column (28) should be corrected with the new electronic table given here.
