Table 1: Parameters for the spectra in Figure 2. The SpDust input parameters are as follows: the total hydrogen number density , the gas temperature , the intensity of the radiation field relative to the average interstellar radiation field , the hydrogen ionization fraction , and the ionized carbon fractional abundance . We also report the CCA spectral parameters , (4).
