Triaxial ellipsoidal bar model with a centrally peaked volume emissivity ρ for the GB of the central 6° × 2° (∼864 pc × 288 pc) of our Galaxy. The inner black dotted rectangle indicates the FOV of our data (∼86 pc × 20.2 pc) and the outer black rectangle indicates the region occupied by the NSD (∼460 pc × 40 pc). Sgr A* is located in the middle of the image. Galactic north is up and Galactic east is to the left. The GP runs horizontally through the center.
