Dust temperature profiles of the cores at two different directions of the cloud, as calculated from the radiative transfer model. The lower line corresponds to the midplane of the flattened structure (θ = 90°), whereas the upper line corresponds to the direction perpendicular to the midplane (θ = 0°). Upper row: G030.50+00.95 Cores A and B; middle row: G31.03+00.26 Cores A and B; lower row: G31.03+00.76 Cores A and B.
