Just Tuning Of Arabic Ajnas

There's an American-Palestinian violinist named Sami Abu Shumays who has created Scala tuning files describing Arabic modal intonation in units of cents so that people can play Arabic maqamat precisely and accurately. His intonation data is very extensive, including some intonations that are localized to specific regions like Egypt, Syria, and Lebanon. Let's look at his intonation and try to provide a rational and intervallic analysis.

We'll look at his intonation in terms of ajnas, i.e. scale fragments, including both the moral tonal ajnas (jins Ajam, Ajam Murassaa, Hijaz, Hijaz Murassaa, Hijazkar, Kurd, Nahawand, Nikriz, Saba Zamzama) and the more microtonal ajnas (jins Bayati, Jiharkah, Rast, Upper Rast, Saba, Saba Dalanshin, Sikah, and Sikah Baladi). 

For completeness, we'll also talk about a few ajnas that Abu Shumays doesn't touch on, namely (Athar Kurd, Lami, Mukhalif Sharqi, Musta'ar, and Sazkar).
