Measured sizes of barlenses plotted as a function of the measured barlength, both given in kiloparsecs. The line shows a linear fit between these two parameters (slope = 0.54 forcing y-intercept = 0). For comparison, the measured sizes of the nuclear features are also shown, with no correlation with the barlength. However, it is important to note that the small nuclear structures may fall below the resolution of S⁴G images (FWHM = 2.1′′).
