Portion of the UCLES spectrum of the symbiotic star RR Telescopii, where the flux is in units of ergs cm⁻² s⁻¹ Å⁻¹, with the expected position of the [Cl II] 6161.8 Å emission feature (line). Also labeled in the figure are the Fe II 6147.1 Å, Fe II 6147.4 Å, Fe II 6149.2 Å, Fe III 6163.7 Å, and He II 6170.7 Å transitions, while there is an unidentified feature at 6150.1 Å. Radial velocity and interstellar extinction corrections have not been applied to this spectral scan.
