The blueCONTINUUM image can also be produced from a (deconvolved)
spectral line data cube by the magentaMAP_CONTINUUM command. Compared
to the method presented in Sec., this has the advantage of being able
to handle spatially variable spectral index, and also spatially
variable spectral line contamination. It has the drawback of limited
S/N for the deconvolution, as already mentionned, unless the spectral
line data cube also contains the continuum emission using one of
the two methods presented in Sec.

Also, the blueCONTINUUM image can be read from a GILDAS data file using command magentaREAD CONTINUUM. And of course, it can be written to GILDAS data file by command magentaWRITE CONTINUUM.
