CubeSum_AT sums all the emission in a cube, regardless of
whether or not it comes from different spectral lines, creating
a zeroth moment map of all emission.
CubeSum_AT output for x.im
Integral (moment 0) of all emission in image cube

CubeSpectrum_AT creates spectral plots (a "CubeSpectrum") at one or more (x,y) positions in the datacube. Alternatively, it can produce a spectrum averaged over a box.
