Real data. Receiver operating characteristic (ROC) curve for the different priors in the photometric matching problem. This curve shows the true positive match ratio versus false positive match ratio. The area below the curve varies with the different priors; the larger the area, the better the performance: uniform prior (red), flux prior (blue), surface brightness prior (green), two-way uniform prior (magenta), two-way flux prior(cyan).
