Variations in the selected molecular ratios with EasyRo values. The C13-16 AA/AIP ratio represents the sum of C13-16 AA peak area divided by that of C13-16 AIPs; C17-22 AAs were not included due to their identification with less confidence in the relatively low-temperature pyrolysates. The n-C17/Pr and n-C18/Ph ratios were extracted from our previous study [34].
