Parameters of the best-fitting models for cuts 1, 2, and 4, described in Sect. 6.3, where Rout is the external radius of the filament and the percentages in the “aggregates” lines give the percentage of voids in terms of grain volume.

Notes. The following lines give the factor by which the opacity at 250 μm is increased, nC is the central proton density, Rflat is the central flat radius, nT is the threshold density above which DHGL populations disappear in favour of aggregates, Mline is the mass per unit length of the filament, and FWHM is the width at half maximum of the hydrogen column density profile.
