CMDs and spatial positions of the point sources detected in the images of the UCHVC AGC 249525, which was included in the sample presented in Janesh et al. (2019) and which we have reprocessed and analyzed with our updated detection pipeline. A stellar overdensity with a statistical significance of 99.26% is detected that coincides with the location of the H I source (green contours). The top-left plot shows the locations of the stars detected in the field (gray points), the stars selected by the CMD filter (red points), the 3′ radius detection circle (magenta), and a reference circle of the same size placed at a random location along the edges of the field. The smoothed surface density map of the CMD-filtered stars appears on the lower left, with the detection and reference circles marked in the same way as in the top-left plot. The CMD in the top right shows all of the sources in the field (black points), the CMD filter (blue solid line), and the CMD-selected stars (red points). The CMDs for objects located with the detection circle and comparison (reference) circle appear on the lower right. The H I contours from the Adams et al. (2016) WSRT study are shown with with green solid lines on the top-left and bottom-left spatial plots; the contour levels are [9, 15, 20, 30, and 40]–10¹⁸ atoms cm⁻².
