In recent years several people have used the IRAS data to produce ([25] - [60]) / ([12] - [25]) two-colour diagrams of late type stars (Van der Veen and Habing 1988; Qing-Quan 1988). The distribution of all these AGB stars are concentrated in a limited area, and any special series of stars are limited on a definite curve which can be represented by an exponential equation like.
