JVLA 1.6 cm continuum map of Sgr B2(S) presented as gray shaded areas and black contours with levels of 5, 10, 30, and 50 × 0.2 mJy beam⁻¹. The reference position is α_J2000 = 17^h47^m20472, and δ_J2000 = −28°23′45120, the peak position of the continuum source. The thin diamond, star, and circle show the positions of NH₃ (7,4), (9,6), and (10,7) emissions. H₂O (McGrath et al. 2004) and OH (Gaume & Claussen 1990) masers are presented as triangles and hexagons, respectively. The color bar indicates the velocity range (V_LSR) of the maser spots. The systemic velocity of Sgr B2(S) is V_LSR = 60 km s⁻¹ (Meng et al. 2022).
