Top: zoom-in of the H₂ outflows from Figs. 2, 3, and 5. The H₂ velocity map of the broad-component emission is shown in color, with overlaid in white contours the H₂ total-intensity map of the broad component and in black contours the HST/NICMOS image from Figs. 2, 3, and 5. Contour levels of the total-intensity maps of the broad component are: 2, 4, 6, 8, 16 × 10^-18 erg s^-1 cm^-2 spaxel^-1 (IRAS 12112+0305); 5, 9, 13, 17 × 10^-18 erg s^-1 cm^-2 spaxel^-1 (IRAS 14348-1447); 1, 3, 9, 27 × 10^-18 erg s^-1 cm^-2 spaxel^-1 (IRAS 22491-1808). The small cross (×) marks the peak of the IR-emission in the NICMOS image, which is presumably the center of the galaxy. The large cross (+) marks the location where the outflow reaches a maximum velocity at zero intensity, and against which we extracted the H₂ spectra shown below. The dashed line represents the direction of the minor axis, as we estimated from the kinematic of the narrow-component disk and the HST/NICMOS imaging (see Appendix A). Bottom: H₂ 1–0 S(1) spectra extracted from a region of five pixels (three pixels both E to W and N to S, as marked with the “+” sign above). The black line shows a double Gaussian fit, consisting of a narrow (red) and broad (blue) component.
