Distribution of parameters for the candidate with 2.37 < BRExcess ≤ 5. The light gray dots represent the 60,671 random LAMOST sources, while the dark gray dots correspond to the sources with 2.37 < BRExcess ≤ 5. The HCSC candidate is denoted as the red dot. The subplot of the first column of the second row is made similarly to that in Figure 3.
