Star-formation relation for Bolocat sources with a photometry aperture radius of 40''shows a weak relation with a large scatter. The contours represent the same source number densities as in Figure 4. The solid black line represents the best linear fit to the log of the data, and the dashed red line represents the extragalactic star-formation relation (Equation (6)), and the dot-dashed blue line represents the Galactic relation for dense gas from Wu et al. (2005). The vertical and horizontal dashed gray lines show the 3σ detection limit in and ΣSFR, respectively.
