Spectra of the 4.7 μm bands of carbon monoxide in absorption, and spectra of the cores of the 0.4 μm resonance lines of ionized calcium in emission, might be used to diagnose the presence of atmospheric inhomogeneities, caused by the action of surface magnetic fields, on stars as diverse as the Sun and the red giant Arcturus.
