In order to avoid the diffuse noise passing the ZS and amplified by the vignetting, and not change the ZS that can change the energy scale depending on the position, have a dynamical cluster seeding threshold.
Since the LY correction can go up to factor 5-6, threshold the seeding correction to max 2.
Few other tunings, the major is raise the median filter window to 6 macro-pixels (was 4).
Situation improves a bit in the vignetted regions:
it seems to clean a bit w/o destroying the long clusters.
