The
CONTINUUM image can also be produced from a (deconvolved)
spectral line data cube by the
MAP_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 CONTINUUM image can be read from a GILDAS data file using command READ CONTINUUM. And of course, it can be written to GILDAS data file by command WRITE CONTINUUM.
