Notes. This table gives fractions of prestellar and starless cores found within various getfilaments and DisPerSE mask images. For the getfilaments masks, upper transverse scales of either ~0.1 pc or ~0.2 pc (i.e., ~50′′ or ~100′′, respectively), were considered. The DisPerSE filament footprints were assumed to be 0.05, 0.1, or 0.2 pc-wide around the nominal filament crests, and both the robust and the raw sample of DisPerSE filaments (see Sect. 3.2 for details) were considered.
