Notes.

^(a)

The upper limit is calculated for the extreme case that the classification of all the unknown objects located in each occupation zone is true, and the lower limit is calculated for the extreme case that the classification of all the unknown objects in each occupation zone is false.

^(b)

The ratio of the number of correctly classified known objects to the total number of the known objects in each of C-rich and O-rich AGBs.

^(c)

Candidate samples.

^(d)

Purified samples residing in the occupation zones in all the three color–color diagrams (see Sect. 2).
