      Description

      The new deblender API appears to have large residuals in most blends and completely fails in certain cases, even when using identical constraints. This ticket will attempt to identify and fix these issues.

          The issue appears to be a problem with using footprints with an even number of rows and/or columns. Since monotonicity has a fixed center location, the operator caused unexpected results in all fields that didn't have odd shapes.

          This had a tremendous effect on both the large residuals in some images and now prevents all the failed cases observed previously. See the current notebook for an example of the current performance.

          Peter, can you take a look at the notebook in the comment above. Fixing the rows and columns seems to have solved all of the problems I was seeing.
