a Discretized experimental and reconstructed spectra. Our dataset has no spectroscopic signatures above 2200 cm−1, which agrees with Spezzati et al.’s heuristic assignment to CO2. b Trace and posterior distribution for σ, the error parameter. The spectra are equivalent at a SNR of 60. c Trace and posterior distribution plots for Pd1. d Means and 95% credible intervals (CI) of the predicted concentrations for Pd1 and bins of Pd2-Pd5, as well as Pd6-Pd20. We choose these bins as the former contains monolayer clusters and the latter bilayer (or larger) clusters.
