Hello, I've noticed that there is a systematic shift of ~20 angstroms in the H-beta peak from center for all of the fits that I've done. Just as a test, we ran the same spectrum through wdmodel and this shift was not present there. I've attached a sample fit for reference. Not sure if this is an easily fixable issue or if others have experienced this as well.
