Table 2
Table expressing the number of stars classified in the thin or thick disc according to the prescription adopted here for each metallicity-stratified group (‘G’).

| Total | 92 | 23 | 115 | 372 | 53 | 425 | 763 |

Notes. The number of stars classified as belonging to either the thick or thin discs is based on their combined errors (described in Eq. 5). Classifications are determined by whether these errors are above (thick) or below (thin) the threshold defined by the quadratic spline adaptation to Recio-Blanco et al. (2014)’s prescription. The columns marked as 1σ+ sum the two preceding columns, as all stars classified above/below the 2σ threshold are also classified above/below the 1σ threshold. In other words, these columns reflect the total count of stars represented by both the orange and cyan shades in Fig. 9 for both discs. The last two columns show the total number of stars in each group and their percentage of the total 1303 stars.
