Relative parallax uncertainty ϵ(ϖ)∕ϖ versus parallax ϖ, in mas, of LPV candidates with ϖ > 0.01 mas. The colour of each point is related to the median(G_BP ) −median(G_RP e) colour of the corresponding star according to the colour scale shown on the right of the figure. Dashed lines are drawn at ϵ(ϖ)∕ϖ = 0.2 and ϖ =0.1 mas, and dotted lines are drawn at ϵ(ϖ)∕ϖ = 0.1 and ϖ =0.2 mas as eye guidelines.
