JVLA 1.6 cm continuum map of Sgr B2(NS) presented as gray shaded area and black contours with levels of 5, 10, 30, and 50 × 0.2 mJy beam⁻¹. The reference position is α_J2000 = 17^h47^m20043, and δ_J2000 = −28°22′41143, the peak position of continuum source Z10.24. The yellow cross shows the position of NH₃ (6,3) emission. H₂O (McGrath et al. 2004), class II CH₃OH (Caswell 1996; Hu et al. 2016; Lu et al. 2019), H₂CO (Hoffman et al. 2007), and OH (Gaume & Claussen 1990) masers are presented as triangles, squares, pentagons, and hexagons, respectively. The color bar indicates the velocity range (V_LSR) of the maser spots. The red cross marks the position of the hot core, Sgr B2(N5), taken from the 3 mm imaging line survey EMoCA (Bonfand et al. 2017). The systemic velocity of the hot core, N5, is V_LSR = 60 km s⁻¹ (Bonfand et al. 2017).
