Spitzer catalogues
We use data from the {\it Spitzer Space Telescope} to search for protostellar associations with all of the dense cores. For L1688 and NGC~1333, we use the young stellar object (YSO) catalogue from \citet{Dunham16}. The \citet{Dunham16} catalogue does not include Taurus, however, so for B18, we use the catalogue of \citet{Rebull10}. We define all dense cores which have peaks located less than 7.05\arcsec, i.e., within half the JCMT SCUBA-2 850 $\mu$m beam size as protostellar cores. For our analysis, we exclude dense cores associated with protostars classified as Flat spectrum, class II, or class III [**CHECK THIS FOR FLATS**]. In these cases, we expect that most of the material associated with the YSO is on scales smaller than can be resolved with the JCMT or GBT, and hence a kinematic analysis on these larger scales could be misleading; our focus is on the starless dense cores, and those associated with very young protostars where little of the material has yet been accreted. [HK notes - will need to make some note of which protostars were considered unevolved enough in the Rebull catalogue, as I don't believe she provided classes or alphas.]
[HK notes - Ronan produced some nice figures showing the protostar distribution for every cloud, which could be included here.]
