Notes.
The CN 2−1 transition consists of 19 hyperfine structure components. The ALMA SPW is centered on the second component listed in the table, which is the brightest hyperfine component of CN 2−1. Because of the line broadening due to disk kinematics, this is blended with the other two listed components.
