Erratum: ``Post-T Tauri Stars in the Nearest OB Association'' (AJ, 124, 1670 )
In Table 3 the F6 V-type spectral standard star HR 7061 is mistakenly aliased as HD 173677 but should be HD 173667. In §7.2 HIP 68282 is mistakenly aliased as ν1 Cen (``nu 1'') but should be υ1 Cen (``upsilon 1'') according to the Bright Star Catalog (D. Hoffleit & W. H. Warren, Jr. [New Haven: Yale Univ. Obs.; 1991]). The same error in SIMBAD has since been corrected. In Appendix A, third paragraph, the units of slope should be K [log(cm s-2)]-1, not K [log(cm s-1)]-1. In Appendix C there is an incorrect sign in the second term in equation (C6), and incorrect color ranges were published for equations (C6) and (C7). Equations (C6) and (C7) provide polynomial transformations between the Tycho (BT-VT) and Cousins-Johnson (B-V) colors. The correct equation (C6), applicable over the color range (BT-VT)∈[0.40, 2.00], isB-V=(BT-VT)-7.813×10-3(BT-VT)-1.489×10-1(BT-VT)2+3.384×10-2(BT-VT)3. (C6)The correct formula (C6) was applied in the paper but transcribed incorrectly to the manuscript. Equation (C7) was published correctly, but the published color range is incorrect. For the color range (BT-VT)∈[-0.25, 0.40], equation (C7) should be used (same as published):B-V=(BT-VT)-0.006-1.069×10-1(BT-VT)+1.459×10-1(BT-VT)2. (C7)We thank John Carpenter for bringing the error in equation (C6) to our attention and François Bonnarel and Christian Nitschelm for pointing out the stellar misidentifications.
