This recent preprint may be of interest to high resolution spectroscopists observing the Balmer lines of symbiotic stars

Re: Modelling Balmer line wings in symbiotic stars
Thank you for the input, David
There's two theories for the formation of broad pedestrials in symbiotics lines:
- scattering (your reference)
- fast wind (+++ 100 km/s) from the hot component
From observationnal results, it is impossible to decide between the two
