We find no clear correlation between the fragmentation level and velocity dispersion, nor between the observed number of fragments and the number of fragments expected when the gravitationally unstable mass is calculated including various prescriptions for `turbulent support'. On the other hand, the best correlation is found for the case of pure thermal Jeans fragm","authors_text":"Aina Palau, Alvaro Sanchez-Monge, Enrique Vazquez-Semadeni, Francesco Fontani, Gemma Busquet, Javier Ballesteros-Paredes, Laura Gomez, Luis A.
