clipFootprintsToNonzero(debResult, log)	Clip non-zero spans in the template footprints for every peak in each filter.
deblend(footprint, maskedImage, psf, psffwhm)	Deblend a parent Footprint in a MaskedImageF.
fitPsfs(debResult, log[, psfChisqCut1, ...])	Fit a PSF + smooth background model (linear) to a small region around each peak.
makeTemplatesMonotonic(debResult, log)	Make the templates monotonic.
medianSmoothTemplates(debResult, log[, ...])	Applying median smoothing filter to the template images for every peak in every filter.
