I find all nufft packages have similar problem. When considering data consistency, y - F(x) remains at a level (when x = FH(y) for initialization) that depends on the density...

> This is based on what sort of normalization? Could you not just normalize the 233 with 232 using multiplication on density compensation..? (233) = F(FH(D*y)) so it has already...

Thanks for your attention. I have tested your advice and this also failed when repeatedly using dcf in adjoint nufft and nufft back to the k-space domain. A little attempt...

Thanks for your patience :)
