Thank you for your comments!

I added a sentence to the abstract that stressed the legacy value of this dataset.

I added a brief description of Pan-STARRS1.

I now mention that the sky aps are determined "by-eye".

I'll stick with 5sigma upper limits.

I added a note about how M_dust is derived via normalizing the SED to the observed data.

I now mention that the DL07 dust opacities need to be updated, and that I'm comparing apples to apples in Figure 5 when analyzing the dust masses.
