Density map of the parallax versus G for Dataset C. The lines are examples of parallax limits below which stars are classified as LPVs (for G_BP − G_RP = 3 mag for the solid line and for for G_BP − G_RP = 5 mag for the dashed line). A rainbow colour-code is used for the density map to highlight the location of the densest regions with respect to the solid and dashed lines. The axes ranges have been limited for better visibility.
