Potential Contaminants:

Sources with ΔTmag < threshold are bright enough to produce the eclipse if they were an EB.

View Modes:
  • Median: Average image - check for clean PSF vs crowded field
  • In/Out: Side-by-side comparison during vs outside transit
  • Diff: Where is the flux missing? If the dark "hole" is offset from the target star, this indicates contamination (false positive)
Interpretation: Trustworthy centroid = well-defined bright spot on dark background.
