2009ApJS..182..474S Erratum: "SFI++ II: A New I-Band Tully-Fisher Catalog, Derivation of Peculiar Velocities and Data Set Properties" (2007, ApJS, 172, 599) Springob, Christopher M.; Masters, Karen L.; Haynes, Martha P.; Giovanelli, Riccardo; Marinoni, Christian Abstract. We were alerted by various investigators (Luis Varga, Hume Feldman, Azalee Bostroem, and Caihong Wang) that the morphological-type correction for the peculiar velocity calculation was not properly applied in the published tables. We have investigated this, and discovered that both the corrected magnitude and peculiar velocities for galaxies with a morphological-type correction (those of type Sb and earlier) were erroneously reported in our tables. The actual calculation of morphological corrections for the construction of the template in Masters et al. (2006) was done correctly, but the processing of parameters into data tables done for this paper included an error in this correction. This error only directly affects the peculiar velocity calculations of the galaxies of type Sb and earlier. However, it indirectly affects the peculiar velocity calculations of the later type galaxies in that the Malmquist bias correction depends on the overall magnitude distribution of the sample. With a slightly different magnitude distribution, the Malmquist bias correction will be slightly different as well. Thus, after fixing the corrected magnitudes, we redid the Malmquist bias correction, and so the later type galaxies also have slightly revised Malmquist bias corrected distances and peculiar velocities now. We were separately alerted by Azalee Bostroem that the correction for standardizing optical rotation curve (ORC) widths to HI widths was incorrectly applied in the template cluster table. Again, the correction was applied correctly in the actual derivation of the template relation, so the peculiar velocities are unaffected by this. However, incorrect values were included in Table 4 for the galaxies with ORC widths. We therefore present revised versions of Tables 2, 3, and 4 in the online version of the journal for which these errors have been corrected. These should replace the originally published tables. Most of the published parameters remain unchanged.The parameters that have been updated are as follows {see text}
