With an algorithm DENDROFIND we identify 51 fragments and compute their sizes and masses. We discuss their mass spectrum and interpret it as being the result of the shell fragmentation process described by the pressure assisted gravitational instability – PAGI. We conclude that the explanation of the clump mass function needs a combination of gravity with pressure external to the shell.
