Name

tabclip - clip a table

Synopsis

tabclip [parameter=value]

Description

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.

Parameters

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.
