NumberDeblendChildSourcesMetricTask¶

NumberDeblendChildSourcesMetricTask computes the number of science sources created by deblending when processing data through single-frame processing (as the pipe_tasks.numDeblendChildSciSources metric). It requires source catalogs (by default, a src dataset) as input, and operates at image-level granularity.

Processing summary¶

NumberDeblendChildSourcesMetricTask reads source catalogs (src datasets, by default) and adds up the number of sources that have a deblending parent in those catalogs. Sky sources, and sources that are themselves deblended, are not counted.
