Fig. 2

Continuum subtracted spectro-images of the ISO-Oph 200 outflow in the H2 1-0S(1) and [Fe II] 1.257 μm lines. Velocities have been corrected for the systemic velocity of the source. Top panels: here the emission in a mainly blue-shifted velocity range is shown to highlight the blue-shifted jet emission only. Black contours begin at 3σ and increase in multiples of 1.5. 1σ = 4.5 × 10−15 erg cm−2 s−1 μm−1. The blue contours show the continuum emission and they correspond to 50%, 75%, and 95% of the peak flux of the continuum. The black stars marks the position of the emission peaks and the emission PA is delineated by the dashed line. Bottom panels: here the emission in the velocity ranges –80 km s−1 to 128 km s−1 (H2 ) and –96 km s−1 to 114 km s−1 ([Fe II]) is shown. This range was chosen to show simultaneously the extended blue and red-shifted low velocity H2 emission which it is argued traces the cavity. The chosen range also shows that there is no red-shifted counterpart to the blue-shifted jet emission and that the cavity emission is not seen in [Fe II]. Contours start at 3σ and increase in multiples of 1.5. 1σ = 5 × 10−15 erg cm−2 s−1 μm−1. The continuum emission is plotted in the same way as for the top panels.
