JHK photometry of population I CN-rich field giants
IR JHK photometry has been obtained for a sample of CN-rich field redgiants. It is found that these giants segregate according to metallicityor CN band strength in the (J-H), (H-K) two-color diagram. A delta (H-K)color-excess index is presented, which correlates with the strength ofthe 4215 wavelength CN band as measured by the delta C(m) index of theDDO photometric system (McClure, 1970). The sensitivity of delta (H-K)as a metal abundance indicator is shown to be relatively small. It issuggested that the CN-rich field giants have colors comparable to manyof the metal-rich giants in the Galactic bulge studied by Whitford andRich (1983), although a few of the bulge giants appear to have higherabundances.
