      Description

      After DM-10271, detection will have two sources of inefficiency due the limitations of lower-level algorithms:

      • Because there's no way to tell SubtractBackgroundTask to just estimate the background without subtracting it, we do an unnecessary subtract and add of a large image.
      • Because there's no way to tell the thresholding code to find Footprints without finding Peaks, we waste time looking for Peaks we'll throw away when doTempLocalBackground is True.
      • Because there's not way to tell the thresholding code to find Peaks within an existing Footprint, we waste a lot of time (80% of the total runtime of SourceDetectionTask) transferring overlapping Peaks from one set of Footprints to another.
