Color–color diagrams of the NEP-Wide MIR source matching with optical data. a) (S7 − S9W) vs. (S9W − S11) and b) (S7 − S9W) vs. (S7 − S11) color–color diagrams. All of the MIR sources having optical counterparts are presented using dark dots in the diagrams. Among them, the star-like sources defined as those with stellarity greater than 0.8 are indicated by the red histogram.
