Overview of dust grain growth in selected Bok globules with one or more polarization holes.

Bok globule Spectral index Derived from Fλ at

CB 541,3 2.99 1.3 mm, 850 μm
CB 1992,3 (B335) 2.09 850 μm, 450 μm
CB 2242,3 2.31 1.3 mm, 850 μm
CB 2302,3 2.81 1.3 mm, 850 μm
CB 2442,3 2.20 1.3 mm, 850 μm

Notes. The spectral index of B335 is derived from the flux at 850 μm and 450 μm, because flux measurements at 1.3 mm are missing.
