RIERA, A. et al. Fabry-Perot observations of HH 1/2. Rev. mex. astron. astrofis [online]. 2005, vol.41, n.2, pp.371-382. ISSN 0185-1101.

We present new Hα Fabry-Perot observations of the HH 1/2 system. Line profiles, barycenter radial velocity maps and dispersion maps are derived from the channel maps of HH 1 and HH 2. The radial velocity barycenter maps of both HH 1 and HH 2 show a general trend of "red-shifted upstream/blue-shifted downstream" pattern. A "direct+scattered" component model for three emitting condensations is qualitatively successful at reproducing the general features of the barycenter and the velocity dispersion of HH 2.
