Notes. [X] denotes log (abundance/solar abundance) of species X.
Upper limit given by Rauch et al. (2013).
Generic model atom (Rauch & Deetjen 2003) that comprises Ca, Sc, V, Ti, Cr, Mn, and Co, constructed with a relative abundance pattern that uses the upper abundance limits of Ti, Cr, Mn, and Co given by Rauch et al. (2013) and 1.0 × 10-7 (mass fraction) for Ca, Sc, and V.
