Abstract
We have discovered that an error was made in computing ion temperatures for some of the results derived from the positive ion data from the plasma science (PLS) experiment on the Voyager spacecraft. The reported results directly affected by this error are the ion temperatures in the inner magnetosphere of Jupiter given by Bagenal et al. (1980) and Bagenal and Sullivan (1981) plus a single ion temperature calculated from Voyager 1 data obtained in Saturn's magnetosphere and quoted by Bridge et al. (1981). The ion temperatures quoted for the torus region in the original Jupiter Science article (Bridge et al., 1979) and all of the ion temperatures in the middle magnetosphere of Jupiter (McNutt et al., 1981) were derived independently and are unaffected by the error.
