The deconvolved size, the mass, and the column density of MMS 6-main are estimated to be 0.32\"x0.29\" (132 AUx120 AU), 0.29 Mo, and 2.1x10^{25} cm^{-2}, respectively. The estimated extremely high mean number density, 1.5x10^{10} cm^{-3}, suggests that MMS 6-main is likely optically thick at 850 um.
