Abstract

Figures 3–11 have an error in that the direction of the offsets should be reversed. Thus, in the spectro-astrometric plots, positive offsets are toward the top of the figure and negative offsets toward the bottom. In the position–velocity diagram shown in Figure 8, positive offsets are toward the left and negative toward the right. The result of this correction is that the orientations of the blueshifted and redshifted lobes of the outflows are now reversed. Thus, for ISO-Cha1 217 the blueshifted flow is the in northeast quadrant with a position angle (P.A.) of 20° and the redshifted flow is in the southwest quadrant (see Figure 2). Similarly, for ISO-Oph 32, the blueshifted flow now lies in the northeast quadrant with a P.A. of 60°. Table 3 has been updated accordingly.
