Notes. (1) The values of ISRF, DGL, and SB_max are in units of 10^-8 erg/s/cm²/ A/sr. The ISRF for different wavelengths are from Porter & Strong (2005). (2) τ and a are the extinction optical depth and albedo of the dust in the sky adjacent to B207 assuming R_V = 3.1. The albedo values are from Draine (2003a). (3) τ_abs is the average absorption optical depth of photons after their first scattering, τ_abs = 0.5(1−a)τ. (4) I_DGL,sky is the diffuse galactic light adjacent to B207, derived by using aI_ISRF(1−e^{− τ})e^{− τ_abs}. (5) SB_max is the peak intensity of the globule after subtracting the nearby background sky intensity. (6) The quantity (0.78 × DGL+SB_max)/ISRF is the ratio of the maximum intensity at the rim of the globule to the intensity of the illuminating interstellar radiation field. (7) The albedo of the cloud, a_c, evaluated from the corresponding ratio (0.78 ×I_DGL+SB_max)/ISRF assuming the forward scattering asymmetry parameter, 0.6 ≤ g ≤ 0.9 from Fig. 6, Witt & Stephens (1974).
