Top panel: HD 39136, a normal curve of our sample (blue filled squares) whose best-fit standard CCM curve corresponds to R_V = 2.85 ± 0.47 (red dotted line). The (magenta) long-dashed line is computed as the seventh model in Table 1 of Weingartner & Draine (2001), R_V = 3.1, including latest updating (Draine & Li 2007); the (green) short-dashed line is our best-fit dust model: the fifth model in Table 3. Bottom panel: HD 12323, a normal curve of our sample (blue filled squares) whose best-fit standard CCM curve corresponds to R_V = 2.30 ± 0.51 (red dashed line); the (green) continuous line is the best-fit dust model: the thirteenth model in Table 3.
