LAS\FOLD [/BOUNDARIES KEEP|DROP]
FOLD copies R into T, and folds a (not yet folded) frequency-switched
The behavior regarding blank values (contaminating or not the resulting
spectrum) is ruled by the SET BAD tuning (see HELP SET BAD for details).
If blank channels are located at the folded spectrum boundaries, they
can be kept (/BOUNDARIES KEEP) or implictly dropped (/BOUNDARIES DROP).
Default is KEEP.
Because of the frequency throw, there are frequencies which are not cov-
ered by all phases (R%HEAD%FSW%NPHAS), typically 1 phase instead of 2.
The resulting channels in the folded spectrum are located at the spec-
trum boundaries. If SET ALIGN second argument is Intersect (resp. Com-
posite), those channels are rejected from (resp. included in) the re-
sulting R spectrum. Default is Intersect.
