Fifty of these are double-barred galaxies: a small-scale, \"inner\" or \"secondary\" bar is embedded within a large-scale, \"outer\" or \"primary\" bar. I provide homogenized measurements of the sizes, ellipticities, and orientations of both inner and outer bars, along with with global parameters for the galaxies. The other 17 are classified as \"inner-disk\" galaxies, where a large-scale bar harbors an inner elliptical structure which is aligned with the galaxy's outer disk.
