Notes. WAME denotes the log-Gaussian equivalent width. The bias in the best-fit peak frequency is expressed as a percentage, where a negative value indicates that the peak frequency fit by the log-Gaussian is lower than the original peak frequency of the theoretical template. The SPYDUST model used corresponds to an ensemble of grain geometries.
