[ADVANCED\]UVPREVIEW [TAPER Ntaper] [CLIP Threshold] [HISTO Nhisto]
[SMOOTH Nsmooth] [/BROWSE [Ataper]] [/FILE UvData.uvt [Drop]]
A fast previewer to figure out if there is signal and what is its spec-
tral shape. The command attempts to find out the line free regions and
to estimate a continuum region.
The output of UV_PREVIEW can be used for further processing commands
(UV_BASELINE and UV_FILTER, UV_SPLIT, SPECIFY, etc...)
If a catalog is defined (see HELP CATALOG), it will also display line
identification (red for detected ones, blue for the others).
The behaviour is controlled by 4 parameters than can be set through
the "KEY Value" optional argument pairs. These are
TAPER Ntaper : number of scale sizes (default 4)
CLIP Threshold : Clipping level in Sigma (default 3.5)
SMOOTH Nsmooth : Number of spectral smoothing (default 3)
HISTO Nhisto : Size of histogram
These values are "sticky": they remain valid until further change, and
they can be listed by
UV_PREVIEW ?
