NumberSciSourcesMetricTask

NumberSciSourcesMetricTask computes the number of science sources created when processing data through image differencing (as the ip_diffim.numSciSources metric). It requires source catalogs (a src dataset) as input, and can operate at image-level granularity.

Processing summary

NumberSciSourcesToSciSourcesMetricTask reads source catalogs (src datasets) and adds up the number of primary sources in those catalogs.
