Comparison of explicitly fitted 
for HCO (black), CH2 (red), CN (green), and N2 (blue) for all dust models from Weingartner & Draine (2001b,their Table 1) with scaling relationship Eq. (16). The large points show the original values of γj from UDfA, the open diamonds show the values calculated using an MRN dust model, and the open squares denote the explicitly calculated values assuming
