Same as Fig. 3, but for the N = 9 → 8 transition of AlO observed with a lower angular resolution of 163 × 132 mas. The map shows a region of the sky ~4 times larger than in Fig. 3 and also encompases Mira B (left continnum source). Gray contours show continuum emission of the binary at levels of 2.5, 5, 10, 30, 60, and 90% of the maximum. The center of the AlO emission, marked with a black cross, does not coincide with that of the continuum of Mira A.
