Notes. 

(a)

Derived from interferometric observations of: millimetre continuum (C1, C1-a, C1-b and C2, Paper II), N2D+ (N and S, Paper I), and ammonia (A1, A2 and C3 this work);

(b)

from the 225 GHz continuum integrated emission (Paper II), assuming that Trot equals the dust temperature and a gas-to-dust ratio of 100;

(c)

from the 284 GHz continuum integrated emission (Paper II), assuming that Trot equals the dust temperature and a gas-to-dust ratio of 100;

(d)

from the 284 GHz continuum integrated emission, assuming a hot core temperature of 200 K (Paper II) and a gas-to-dust ratio of 100;

(e)

core not well-defined in the ammonia maps.
