Classification of images based on the value of Δx. The top plot shows Δx for 19 000 UBr measurements of HD 138690 (γ Lup) in the Sco I field. The two horizontal lines indicate the high (Δhigh = 36 pix = 0.75X, X = 48 pix) and low (Δlow = 12 pix = 0.25X) cut-off thresholds. The three images shown below correspond to three cases, from left to right: useful image (Δlow< Δx = 24.91 pix < Δhigh); image with overlapping profiles (Δx = 2.99 pix < Δlow); image with profiles too far from each other (Δx = 37.20 pix > Δhigh).
