Notes. Uncertainties listed for the meteoritic abundances are purely statistical but a systematic and fully correlated 0.02 dex uncertainty should be included for all elements (Sect. 3.3). The last row reports the total Z/X, where the abundances of volatile elements are always taken from the photospheric scale. For the meteoritic scale, the second uncertainty source reflects the fully correlated uncertainty from transforming the cosmochemical scale to the astronomical scale. See the text for details.
