Comment (by David Boyer):

@Roland Haas I attempted the changes of the parfile as mentioned in the ticket. I’m posting what I changed in the parfiles and the plots I got. I would like to hear your opinion on if it is okay, or if there is another fix you suggest.

Original parfiles:

ML_BSSN::harmonicN           = 1      # these set:
ML_BSSN::harmonicF           = 1.0    # dot[alpha] = - alpha A
ML_BSSN::evolveA             = 1      # dot[A] = dot[trK]
ML_BSSN:--
