Pre-supernova yields are being considered. A comparison between the production factor plots is done between 2 studies: one using the Anders & Grevess 1989 solar abundances (the present study) and the other making use of the Lodders 2004 solar abundances (previous study) for the initial composition of the masive stars being considered.
