This is an implementation of robust/Briggs weighting for images, where robust_param is used to encode the robust scaling. It ranges from -2 to 2, where -2 is close to uniform weighting and 2 is close to natural weighting. Below are simulations of point sources in dirty Stokes I for robust weightings of -2, -1, 0, 1, and 2 (no noise).
Here is a locked DS9 tiled image:
And again, oversaturated
And a gif of the automatically made FHD images
The extreme ends look correct (-2 ~ uniform, 2 ~ natural), but I have no frame of reference for in-between values. It would be great if someone experienced in what robust weighting looks like could advise if this is the normal behaviour.
