Legacy Survey Data Release 9 Blue Horizontal Star candidates

We use objects from Legacy Survey Data Release 9 (Dey et. al 2019 to construct a catalogue with 95446 objects containing "release", "brickid" and "objid". These three parameters provide a unique identifier hash (check here for details ). The catalogue also includes "R.A.", "Dec.", the extinction corrected "g_0", "r_0", "z_0", photometric bands, the colour "grz", the absolute "M_g" magnitude, and the probability of a stellar object being a BHB star, "P_BHB".
