Observed hyperfine manifolds of CN(1–0) at 113.5 GHz (top) and of CN(2–1) at (bottom) toward L1498 as measured with the IRAM-30m telescope (Hily-Blant et al. 2010). For CN(1–0), the five hyperfine lines are shown separately, with their relative intensity indicated at the top. The best-fit model is shown in red, and the residuals are shown below each spectrum. The offsets are indicated on the right of each panel. The x-axis is the LSR velocity, and the intensity is on a main-beam temperature scale.
