Notes. Elements that are commented on are those for which the adopted proto-solar abundances (Sect. 5) are not based on spectroscopy of the solar photosphere; we caution that the differences between solar and CI abundances show a trend with condensation temperature (Sect. 3.3), which should be taken into account when estimating the Solar System composition.
