Consistency of implicit and explicit method. Comparison of N iiiλλ4634 − 4640 − 4642 profiles from model “T3740”, for calculations using a different treatment of DR to the 3d level. Implicit method (solid/black), explicit method (dotted/red), explicit method with oscillator strength for the stabilizing transition increased (dashed/blue) and decreased (dashed-dotted/black) by a factor of two.
