Builds a compact evidence table for candidate clump footprints. A candidate is marked as accepted when it is spatially resolved and has sufficient local compactness and local SED-anomaly evidence.

)Arguments
- clump_labels
Integer clump-footprint matrix.
- score_info
Result from
compute_clump_score().- min_pixels
Minimum number of pixels in a clump footprint.
- min_peak_score
Minimum peak combined clump score. Use
NULLto skip.- min_median_score
Minimum median combined clump score. Use
NULLto skip.- min_peak_contrast
Minimum peak local-contrast score. Use
NULLto skip.- min_peak_sed_anomaly
Minimum peak local SED-anomaly score. Use
NULLto skip.- high_score_threshold
Threshold used to count high-score pixels.
- min_high_score_pixels
Minimum number of pixels above
high_score_threshold.- probable_peak_score, probable_peak_contrast, probable_median_contrast, probable_peak_sed_anomaly
Looser thresholds used to mark candidates as
"probable"clumps.probable_median_contrastis a compactness/coherence floor that helps reject broad galaxy-profile pieces with coherent SEDs but little local brightness contrast.- clump_relax
Single global permissiveness factor for the evidence cuts, bounded to
[0, 1].0is conservative,0.5keeps the supplied thresholds close to their nominal values, and1is permissive. Internally the score/contrast thresholds are rescaled smoothly around0.5.
