Abstract
The analyses presented in the first three papers of this series are revised to include more accurate gf-values and damping constants. The largest changes are in the chromium, manganese, and nickel abundances derived from singly ionized lines. The agreement with the values from neutral lines of the same element is improved. The microturbulent velocities determined from neutral and singly ionized lines by demanding that the derived abundances not be a function of equivalent width were checked by performing similar calculations on lines of selected atomic species and by studying the rms scatter of individual line values as a function of assumed microturbulence. On the whole the adopted values of microturbulence appear to be well determined.
