Abstract
We have studied the HH objects around NGC 7129 using Her emission prof iles, obtained with the CIGALE scanning Perot-Fabry interferometer. Fr om these, we have derived the position dependence of line profiles, ce ntroid velocities and velocity dispersion. HH 103 and GGD 35 have broa d and double-peaked profiles. One extended are-shaped HH object was al so confirmed. The shock velocities and orientation angles are calculat ed from profiles and compared with observations.
