[ADVANCED\]MAP_CONTINUUM [DIRTY|CLEAN|Other] /METHOD SCM [Threshold
[MaxIter]]
Compute the continuum based on the per-pixel spectrum. Each spectrum
is sigma-clipped until convergence of the noise. The method is similar
to the GAUSS method, but more robust at the expense of lower speed be-
cause of the iterative median clipping. Threshold is the number of sig-
ma used for clipping. MaxIter is the maximum number of clipping opera-
tions performed (default 6).
The method does not deliver a spatially independent noise, but adapts
the bandwidth to the line free zones for each pixel. It may fail for
pixels with are close to line confusion, though less than the GAUSS
method.
