We identify 655 BHB stars in this non-kinematically selected sample. We calculate the luminosity function of field BHB stars, and find evidence for very few hot BHB stars in the field. 2008AJ....135..564B https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/135/564 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003) J/AJ/126/1362 : Century Survey Galactic Halo Project.
