RGSpace smoothing width
I've got the impression that the smoothing width for RGSpace is currently not correct in master. Please try this code:
from nifty import * x = RGSpace((256,), distances=1.) f = Field(x, val=0) f.val = 1 sm = SmoothingOperator(x, sigma=50.) plo = plotting.RG1DPlotter(title='test.html') plo(sm(f)) g = sm(f) g.sum()
The Gaussian bell is only half as broad as it should be. I fix is given in dc16a255
@dpumpe Could you please check, if this makes sense?
@mtr Could you please check, if the formula for smoothing on the sphere is correct? https://gitlab.mpcdf.mpg.de/ift/NIFTy/blob/master/nifty/spaces/lm_space/lm_space.py#L169
