I wrote some jupyter notebooks for a stack overview at the Belgrade meeting, you can find them at
They use the data file “example1.fits” that Jim put up on dropbox (it’s a single calexp from ci_hsc) – if there’s interest I could push it to github.
The README describes what’s there; a simple use of various tasks to do single-CCD processing and some variants (add Kron; change the PSF model; tune detection) and a couple to poke at the deblender and illustrate what’s in an Exposure.
