Comparison between asteroseismic and TGAS parallaxes. The markers indicate the evolutionary state of the star, including the red giant branch (RGB or AGB), the red clump (RC), and the secondary clump (SC). The red line shows the 1:1 relation. The black line shows the linear relation obtained from an orthogonal distance regression (ODR), which includes uncertainties on both parallax estimates. The best-fitting relation is ϖ_seis = (1.21 ± 0.07) × ϖ_TGAS−(0.12 ± 0.08). The shaded blue region shows the 1-σ confidence interval around the best-fitting relation.
