Default: None, which results in slicing at 0 in all direction
of `slice_across`.

max_resolution : Tuple of int, optional
A tuple of 2 integers, indicating the maximum resolution of the
restructed 3d array. This is only used for thetaMode geometry.

plot : bool, optional
Whether to plot the requested quantity
