Mode identification precision for a sample of 50 stars using different numbers of latent parameters. The differences between the radial mode frequencies of the PCA method and PBjam are shown in relation to that of δν₀₂ from PBjam. The shaded regions indicate the 68% interval of the observed frequency differences for different numbers of latent parameters used in the model, and the solid colored lines show the median values in each frequency bin. For reference, the dashed line denotes complete agreement between the sets of mode frequencies.
