Notes. (a)Flag(p) indicates whether we estimated p using the radially-averaged cut (denoted A), or the “best” (lowest-χ2) cut (denoted B). (b)These ranges express the range of values plus or minus uncertainties that we get depending on whether 70 μm data are included in the greybody SED fit. See also the note about N12 under Table 3. (c) S26 is not only more than twice as far away as the other sources, but is also thought to contain at least one outflow seen pole-on (Trinidad et al. 2003).
