CMDs of both MeerLICHT (left) and Gaia DR3 (right) data. The blue data points represent the selected sdB candidates from the colour classification schemes. The open orange circles represent EBs identified from the sdB candidates, while the red stars correspond to candidates with sinusoidal variations. Even though white dwarfs are also selected, we do not exclude them from our analysis as they could be relevant to the study of sdB-white dwarf binary systems.
