Notes. (a) Molecular parameters from the CDMS database (Müller et al. 2001). (*)The CN 2− 1 transition consists of 19 hyperfine structure components. The ALMA SPWs are centered on the brightest hyperfine components of CN 2− 1, indicated by an asterisk. Because of the line broadening due to disk kinematics, each of the CN 2–1, J = 3/2–1/2, F = 5/2–3/2, and CN 2–1, J = 5/2–3/2, F = 7/2–3/2 lines is blended with the adjacent hyperfine components reported in the table. The integrated line intensity refer to the sum of the blended components.
