Number of ``P'', ``U'', ``C'', ``D'',``M'', ``R'' and not-classified (`` '') stars, above the positive threshold ( $T_{\rm h}$ ), between the positive and negative thresholds ( $T_{\rm h}=T_{\rm m}+{\rm err}_{+}$ , $T_{\rm l}=T_{\rm m}-{\rm err}_{-}$ ), and below both of them. $T_{\rm m}$ denotes the threshold calculated according to the method presented in Fig. 3.
