varying beams spectral cube

[gvdsteene]

I have a varying beams spectral cube. The casa beams table has disappeared after cutout. None of the result images has a beam value.

Howto fix it please ?
How are beams handled ?

@betacygni I think we should force convolution to a common beam, or at least check that a single beam is a good approximation, before running statcont on data. But, also, this suggests the need to refactor statcont to use spectral-cube for IO.

Yes, I agree. Use the tools in astropy Varying_resolution_spectral_cube for IO, to select good beams, mask_out_bad_beams, calculate average_beams, take it as common beam, and convolve to it. if needed.
