Controls the damping (in the first iterations (specified by CFOUR_SCF_EXPSTART via Dnew=Dold+X/1000∗(Dnew−Dold) with X as the value specified by the keyword. The default value is currently 1000 (no damping), but a value of 500 is recommended in particular for transition metal compounds where the SCF convergence is often troublesome.
