|
Clip non-zero spans in the template footprints for every peak in each filter. |
|
Deblend a parent |
|
Fit a PSF + smooth background model (linear) to a small region around each peak. |
|
Make the templates monotonic. |
|
Applying median smoothing filter to the template images for every peak in every filter. |
|
