Insights into bar ageing. We display the normalised bar lengths (left panel) and normalised bar strengths (A2- right panel) for our sample by galaxy size. We also present the linear regression (dotted black line) for 1000 bootstrap repetitions, the Pearson correlation coefficient r, and the associated null hypothesis p-value. For the two properties, we find trends of correlation. For the bar length, the associated p-value is smaller than 0.05, while for A2 its p-value is ∼1. These results are in agreement with the scenario in which older bars are longer and stronger.
