Reduce galaxy “shredding” when deblending
If galaxies have substructure, such as face-on spirals, the process of identifying peaks can “shred” the galaxy into many pieces. The templates of shredded galaxies are typically quite similiar because they represent the same galaxy. We try to identify these “degenerate” peaks by looking at the inner product (in pixel space) of pairs of templates. If they are nearly parallel, we only keep one of the peaks an reject the other. This behaviour is enabled by the removeDegenerateTemplates option to SourceDeblendConfig; by default, it is disabled.
