The multi-resolution tutorial uses a HSC PSF with 31 pixels. This is apparently too small and creates ringing in the oversampled PSF (which defines the diff kernel):
plt.imshow(obs_hsc._diff_kernels.image[4], vmax=1e-6)
yields Other HSC bands are similar. This should affect the results of the resampling+convolution operation.
This issue addresses two aspects:
HSC PSFs are usually 41x41 or 43x43 pixels. So you should be able to test with the full HSC PSF to see if truncation is the issue.
