\caption{Standard c2d conversion factors for masses and column
  densities from dust emission. For each bolometer camera employed by
  the c2d collaboration we list the effective wavelength, the half
  power beam width, the dust opacity at the effective wavelength (per
  gram of ISM), the conversion factors between intensity and column
  density, and between integrated flux density and mass (this for a
  distance of $100~\rm pc$), respectively.\label{app_dust-tab-survey:1}}
