Bar-b/p strength correlation: distribution of all thin+thick models in maximum bar strength – maximum b/p strength plane. The maximum bar strengths are taken from Ghosh et al. (2023), whereas the maximum b/p strengths are determined from Eq. (1). The colour bar denotes the thick-disc mass fraction (f_thick). Different symbols represent models with different geometric configurations (see the legend). The maximum strength of the bar correlates overall with the maximum b/p strength, and this remains true for all three geometric configurations.
