Inferred model parameters compared with input model parameters for two cases: Dataset-short (top row) and Dataset-long (bottom row). Posteriors were calculated for 500 test spectra from the test dataset. The medians of the posteriors were derived from 1000 samples for each of the 500 test spectra, and the error on the median was determined from the 68% quantile of the distribution. A linear regression coefficient was calculated for each parameter across the 500 test samples.
