- Abstract
We present a four filter technique, based on the method of Wing (1971), to identify and characterise the late-type stellar content of extragalactic systems. Two narrow band filters centred on spectral features of TiO and CN allow us to distinguish between AGB stars of different chemistries [M-type (O-rich) and C-type (C-rich)]. Results for the Local Group galaxy NGC 147 are presented as well.
