Library contains a large number of radio spectral image cubes

An interesting service would be to generate 1-D spectra from cubes on the 
fly.  In addition to the usual search paramters, users would have to 
provide a spatial resolution.  This service would be analogous to an
image cutout service in that the output is generated to user specs
on-the-fly from the underlying data.
