Hormoz Farhat was not a practicing musician, so I would not rely too much on his thesis and book. For sources and details of Persian tuning please see my website http://members.shaw.ca/persianney section techinque-fingering and tuning. In terms of lilypond support for Persian music the koron and sori glyphs are all that's needed for notation, but for midi rendering we'd need also at least the 20 cent flat note, which is not notated but considered part of tuning. Also the minor second is often small up to 10 cent.
