Notes. The flux ratio is estimated by considering only the flux associated with structures where agreement is found. The fluxes are normalised with respect to the total flux in all the structures where agreement is found for the five main structure types. When determining the statistics for the association with the massive star forming(MSF) clumps we only consider structures outside of the inner 10° of the Galactic centre where the matching between ATLASGAL and massive star formation tracers is complete (for details see Urquhart et al. 2014c).
