The CONTINUUM image

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.
