The main data table contains large numbers of pairs
of entries for the same stars. They are separated by ~1"
and have similar but not identical photometry, based on
different images in the dataset, which were obviously not
well linked astrometrically.
Analysis of the results should also take note of the
transformation equations 1 to 5 in the paper, notably the
large (~0.055 mag) zero-point uncertainties, and the
anomalously low V-band extinction coefficient. Such problems
are not uncommon with single-night photometry.
