Fig. 2


Examples of detected submm-RRLs (upper panels) of AGAL037.874−00.399 and AGAL332.156−00.449 and their corresponding mm-RRLs (lower panels) from Kim et al. (2017). The vertical purple dashed lines indicate the systemic velocity measured with H13CO+ (1−0) lines. The different colors present different submm/mm-RRL transitions detected in this paper and Kim et al. (2017). In flux unit, 1 Jy corresponds to ~0.025 K for the APEX 12 m, 0.169 K for the IRAM 30 m, and 0.045 K for the Mopra 22 m data.
