摘要：
The known stellar chromospheric activity indices, R(K) and DELTAF(K), and the index A(K) proposed by the present author, are compared with a new index, W(K), which is color-independent [Robinson et al. ApJS 74, 891 (1990)]. 1 have found that for stars cooler than 5100 K, only the index A(K) is tightly correlated with W(K).
