Positive changes are red and negative changes are blue in the difference image. Candidate markers show the type of difference candidate, not independently detected sources in each epoch.

Candidate markers match the current table page. Select a marker or candidate to inspect its exact pixel position.

These are algorithmically identified candidates, not scientifically validated detections. Significance is exploratory and depends on the variance and quality maps; the noise model still needs scientific calibration. Pixel coordinates refer to the image, not sky coordinates.
