Notes. is the number density of the species and n is the number of measured lines. The Mn and Ga abundances are given taking into account or ignoring HFS effects. For comparison purposes, the last column lists the (rescaled) solar abundances derived from 3D hydrodynamical model atmospheres (Asplund et al. 2009).

The gallium abundance is particularly uncertain because it depends on the treatment of the blended Ne i λ6334 line.
