Mid-plane dust temperature maps (color, all maps on the same scale) of all six globules studied in this paper, derived with the ray-tracing inversion technique and overlaid with contours of the hydrogen column density (white: 10²¹ and 10²² cm^-2, black: 0.5 and 5 × 10²¹ cm^-2). Yellow squares indicate the center positions of the starless cores as listed in Table 1 and in Launhardt et al. (2013). Asterisks indicate the positions of embedded protostars (see Launhardt et al. 2013).
