Examples of 63 pixels × 63 pixels triplet image stamps of our compiled datasets. The top-left part of the figure depicts two real sources in g-band and each row represents a real detection, showing the science image stamp, the reference image stamp, and the difference image stamp of the real detection from left to right respectively. Similarly, the bottom-left, top-right, and bottom-right of this figure display two real detections in the r-band, two bogus detections in the g-band, and two bogus detections in the r-band respectively.
