Notes: NA = not applicable because of absence of methylhopanes or methylhopanones, and of alkenones in specific samples. Compound codes are described in Tables T15
and T16. Compound ratios and carbon number distributions are based on intensities in total ion chromatograms, except for steroidal and 17(21)-hopene carbon number ratios, which are based on distributions in diagnostic mass chromatograms.
