The Perils of Clumpfind: The Mass Spectrum of Sub-structures in Molecular Clouds

Jaime E. Pineda, Erik W. Rosolowsky, Alyssa A. Goodman

We study the mass spectrum of sub-structures in the Perseus Molecular Cloud Complex traced by 13CO (1-0), finding that $dN/dM\propto M^{-2.4}$ for the standard Clumpfind parameters…
