Effective stellar yields - suplementary material

V3: more yield tables, and fix to the units of the stellar lifetimes in the header. also added 'primary only' table, where the primary is used as if it was a single star without any other considerations. V2: Corrections to the net yield tables Suplementary material for Kemp and Kaur 2025: Binary stellar evolution yields in galactic chemical evolution calculations. Includes pre-computed, machine-readable effective stellar yield tables suitable for GCE calculations, as well as a complete database of figures for all isotopes.
