Sample Phoenix spectrum

Sample Phoenix spectrum of a K=11 mag field red giant in the Large Magellanic Cloud. This spectrum consists of a combination of three 20-minute integrations using a 4-pixel slit. This spectral region is dominated by CO 2-0 vibration-rotation lines from both carbon-12 and -13, although two atomic lines are identified, as well as the R9 line from HF (1-0).
