Continuum-subtracted spectra at five different positions along the outflow (see Fig. 1 and Table A.1).

Table A.1

H2 line fluxes.

Appendix B: Outflow width and morphology

thumbnail Fig. B.1

Width of the H2 1-0S(1) jet-like structure as a function of the distance from the source. The jet width has been estimated by extracting 2-pixel-wide vertical slices to the average H2 spectral image presented in Fig. 1 and fitting a single Gaussian function. Zero offsets correspond to the source positions.
