The referenced paper describes the compilation of the second Kiso UV-Excess galaxies survey as KUG2 catalogue. The result is shown in VII/261. The first survey catalogue KUG1 is shown in VII/179. As is described in the paper, there are some differences between KUG1 and KUG2, e.g. in photographic plates used and the observation condition in the surveys, such as emulsions, exposures or seeing sizes. The homogeneity of these KUG surveys is rather low, but their catalogues form a somewhat large collection of UV-excess/blue galaxies. In these circumstances, we intend to merge both catalogues, upon requests from investigators working in follow-up observations of these galaxies. In the process of catalogue merging, we met a systematic difference between the first (KUG1) and the second (KUG2) surveys in overall properties of objects, such as brightness, degree of UV-excess and morphological type. This mainly originates from differences in the observation condition and personal errors in the survey. We scrutinize and discuss those differences and errors, and finally merge into a comprehensive catalogue of KUGs (KUG2000) in the machine-readable form including near ten thousand UV-excess galaxies.
