High-resolution (18.2″) column density views of filament 8 and its embedded cores. All maps are shown from 10²¹ to 2 × 10²² cm⁻². Panel a: high-resolution (18.2″) column density map. Panel b: clean-background and core-subtracted filament image that was reconstructed over the full range of spatial scales. The crest of the filament is shown with a blue-dotted line. Panel c: five robust prestellar cores that were identified along this filament (marked by FWHM Gaussian ellipses), which are regularly spaced with measured projected spacings of 0.17, 0.16, 0.15, and 0.18 pc from south to north, respectively. The mean core spacing is 0.17 ± 0.01 pc. Panel d: detected cores overlaid on the filament.
