Eta definition is so far as: S_L/(S_R+S_L). This definition, although is perfectly fine, is less pictorial than S_R/(S_L+R_R) because the latter identify the left side of the histogram with the left channel (and the right side with the right channel). While the former is the inverse. Therefore, it could be better to introduce and propagate the new definition
