Caption: Figure 17.
The relationship between ﹩\mathrm{log}({F}_{{\rm{X}}}/{F}_{\mathrm{bol}})﹩ and BP – RP. The color bar shows ﹩\mathrm{log}({\rm{Distance}})﹩. Hollow triangles with black edges denote stars without flares, while hollow circles with red edges denote stars with flares. The upper panels correspond to the low-resolution data, and the lower panels correspond to the medium-resolution data.
