Distribution of the ratio of the slit length l_s, at which the pattern speed converges to a constant value, to the projected bar length along the semimajor axis, l_p. There are 538 barred galaxies (weak+strong) in the analysis. The inclination angle of all the galaxies is around 45°. Furthermore, the PA of the bars is around 45°. Therefore, $\widehat{l}\simeq l_s/R_{\text{bar}}$. The black line shows the best fit log-normal distribution function. More than 26% of the galaxies require $\widehat{l}\le 2$.
