AMR for three different datasets: [1] Nissen’s dataset (72 stars, top row), [2] stars that we analyzed from Nissen’s dataset (52 stars, second row), [3] dataset under investigation in this work (485 stars, third row), [4] dataset from Miglio et al. (2021) (2785 stars, bottom row). The right column represents the d_z separation parameter (Sect. 3.1) where the vertical dashed line represents the location of the Nissen’s data drop, the dark blue region is the measurement uncertainty, and the light blue region is the quadratic sum of measurement and statistical uncertainty.
