Concluding remarks: a progress report on our understanding of jets

The authors comment on the talks given at the Torino Workshop on astrophysical jets. The observations presented have not revealed a clear picture of nuclear jets. Concerning large scale jets, people begin to find systematic patterns in the variety of parameters and morphologies. So, this kind of jets is paid most attention to during the Workshop. The authors discuss the general consensus in the basic parameters of jets arisen from the preliminary data. Propagation and confinement of jets, the role of magnetic fields, and some observational tests are briefly reviewed. A final paragraph deals with the origin and termination of jets. (G.J.P.)
