The dangers inherent in using fully automated data processing for large data sets are exemplified by examining the eclipsing binary stars identified via the Detached Eclipsing Binary Light curve fitter. The software may have confused eclipsing binaries with other types of low amplitude variable stars and it is estimated that over a quarter of the 10,862 variable stars listed may have been misclassified.
