Notes. The listed β values are the 25%, 50%, and 75% percentiles for the clumps in the P(χ2 ) = 25% samples. (a) Filtering scale in the SCUBA-2 map making. (b) Small or large masks made based on Herschel data. See Appendix C. (c) Apertures corresponding to Fellwalker clump footprints (τall) or, within them, only pixels above the median τ(250μm) value (τhigh). (d) U refers to original SPIRE data. (e) F refers to SPIRE maps processed through the SCUBA-2 pipeline.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
