JVLA A-configuration spectra of NH3 transition lines toward Sgr B2(N). The dashed red lines indicate the systemic velocities of the associated hot cores. VLSR = 64 km s−1 for N1, and VLSR = 74 km s−1 for N2 and N3 (Bonfand et al. 2017). Main beam brightness temperature scales are presented on the left hand side of the profiles.
