Colour-magnitude diagram of the cluster Biurakan 2. The black dots are members of the cluster according to Hunt & Reffert (2023), and the red dots are our CP star candidates. The PARSEC isochrone (Bressan et al. 2012) was computed using the A_V and log t values from the catalogue of Hunt & Reffert (2023) and using solar metallicity (Z = 0.0152). To "fit" the cluster, they were shifted according to the distance of the cluster, which was also taken from Hunt & Reffert (2023).
