tabclip - clip a table
tabclip [parameter=value]
tabclip
removes points from a table based on some "smoothness" criteria. Examples
are when there is a jump larger than a critical amount it can be flagged.
Or when the derivative exceeds a certain amount.
Fitting programs, such
tabnllsqfit(1NEMO)
can also be used to remove points that are not close
to a global model.
The following parameters are recognized in
any order if the keyword is also given:
- in=
- Input file name (an ascii table)
[???]
- out=
- Output table [???]
- xcol=
- x coordinate column [1]
- ycol=
- y coordinate column [2]
- deriv=
- Clipping if abs(derivative) exceeds
this value []
- eta=
- Clipping if the value predicted from a 2nd order polynomial
value exceeds the Y value by more than eta. Default: not used.
- logic=and|or
- When a left and right side criteria is applied, this determines the outcome
of the clipping. and requires both to be satisfied, or requires only one.
[Default: and].
- nmax=
- Hardcoded allocation space, if needed for piped data.TP
comment=t|f Keep the clipped points as comments in the output file? By default
they are left out.
