      Description

      This is a port of HSC-1353 and HSC-1360.

      Descriptions from HSC:

      HSC-1353

      We typically get a large number of junk detections around bright objects due to noise fluctuations in the elevated background. We can try to reduce the number of junk detections by adding an additional local background subtraction before object detection. We can then add this back in after detection of footprints and peaks.

      HSC-1360

      I forgot to set the useApprox=True for the background subtraction that runs before footprint and peak detection. This will then use the Chebyshev instead of the spline.
