According to my humble opinion it's in maqam Sedaraban that quite suits base and range.

Maqam Sedaraban
A downward movement characterizes this maqam. It's scale consists of a sequence of chromatic subunits, common in Arabs and Turks. The differeces appear in the 'reading' of the whole scheme.
Ascending scale
The Arabs "read" the sequence:
Hijaz 4chord from Yeghah (low Δι) / Nikriz 5chord from Rast (Νη) and again / Hijaz 4chord from Neva (δι) / Nikriz 5chord from Gerdaniye (high νη).
Nikriz is a special feature of this maqam according to the Arab "reading" (see 1)
Descending scale:
Here most chromatic subunits become diatonic (see 2)
Byzantine music equivalent:
Actualy Sedaraban is a transposed scale of another maqam as the "sed" prefix declares. Thus there is no direct match in Byzantine music. It could be regarded as Echos plagal second transposed down to low Δι. Like "plagal" of plagal second if the latter had theoretical substance according to Byzantine Octoechos.
