      Description

      Ikeda-san has reported that the background tweak being applied in the DynamicDetectionTask is excessive when there are bright stars in the field.

      On investigation, found that sky objects are correctly avoiding the DETECTED areas, but the DETECTED area isn't anywhere as large as it seems just by looking at the image because the extended emission from the star is being purposely suppressed by the code (so the deblender isn't overwhelmed; this is the "wide temporary background" feature).

      Suitable results can be obtained by doing an explicit background subtraction (using the base_LocalBackground measurement algorithm).
