During gridding of the dirty or residual image, each visibility value is
1598
1598
multiplied by a weight before it is accumulated on the uv-grid.
1599
1599
The PSF's uv-grid is generated by gridding only the weights (weightgrid).

weighting='natural' : Gridding weights are identical to the data weights
1602

from the MS. For visibilities with similar data weights,
1603
1603
the weightgrid will follow the sample density

pattern on the uv-plane. This weighting scheme
