fft_dimnames

File Purpose: make it easier to deal with renaming fft dimensions

Easiest would be if always ‘dim’ –> ‘freq_{dim}’.

However, dimname should include ‘rad’ if rad=True.

Additionally, there are well-known custom names for some rad fft dimensions,

e.g. when rad=True, ‘x’ –> ‘k_x’, and ‘t’ –> ‘omega’.
