That is interesting! So, implicitly we assume that area implies continuity while number can be no-continue. Makes sense. Thanks for the clarification.

That is an interesting point!

Curretly, all the "area"s are indeed numbers of pixels, but not all "numbers" are areas!

The sigma-clip number column gives the number of pixels used for sigma-clip measurements. The sigma-clipping may result in non-contiguous "area"s and result in confusing the users. Also, mixing the spatial meaning of "area" with sigma-clipping will further confuse readers.

If this doesn't convince you please feel free to continue the discussion here; but for the time being, I think it is better to close this "bug" ;-).

I would be necessary to change the 'sigclip-number' parameter to 'sigclip-area'. The reason is that all parameters related to the measurement of the number of pixels contain 'area' instead of 'number'.
