[CLEAN\]UV_RESIDUAL [MODE] [Arg1 ... ArgN] [/FIELDS List]
This command subtract Clean components OR fit results from the last
UV_FIT command, depending on specified argument MODE if present (can be
CLEAN or UV_FIT), or on whether CLEAN (or its specialized versions HOG-
BOM, CLARK, etc...) or UV_FIT was done last if not. The residual UV data
are available in SIC structure UV_RESIDUAL, and can be written by WRITE
UV_RESIDUAL command.
The UV_RESIDUAL data can also be selected for further imaging by
UV_MAP (and thus UV_RESTORE) or displayed by SHOW UV using command
UV_SELECT. MODEL and UV_RESIDUAL are complementary commands (UV_DATA =
UV_MODEL + UV_RESIDUAL); see HELP UV_RESIDUAL Note however.
For the Clean component the syntax is
[CLEAN\]UV_RESIDUAL [CLEAN] [Niter]
that subtracts the Niter first (default all) Clean Components from the
UV data.
For the UV_FIT results, Clean component the syntax is
[CLEAN\]UV_RESIDUAL [UV_FIT] [F1 .. Fn]
that subtracts the F1 to Fn fitted functions (default all) from the UV
data.
