Exact excerpt

Since evolutionary models of brown dwarfs are untested at young ages and planetary masses, the mass estimates for the new members of IC 348 are subject to systematic errors. ... Mass estimates for young brown dwarfs have systematic errors that can differ from one study to another ... which can make it difficult to reliably compare the masses reported for planetary mass brown dwarfs.
