FractionDiaSourcesToSciSourcesMetricTask¶
FractionDiaSourcesToSciSourcesMetricTask computes the fraction of science sources that become DIASources when processed through image differencing (as the ip_diffim.fracDiaSourcesToSciSources metric).
It requires source catalogs as input, and can operate at image-level granularity.
Processing summary¶
FractionDiaSourcesToSciSourcesMetricTask reads source catalogs (src and deepDiff_diaSrc datasets, by default) and counts the number of sources.
It then computes the ratio of DIASources to science sources for those catalogs.
Non-primary sources are excluded from computations.
