Description:
This program uses
Kappa stats to calculate
mean and standard deviation of an NDF. It then uses
Kappa thresh to set the values at
±n-sigma to
BAD. The clipped data are written to NDF_clip.sdf.
Usage:
sigclip NDF SIGMA
Parameters:
NDF (Given)
The required dataset
SIGMA = REAL (Given)
The clipping level
Examples:
sigclip test 3.0
Clips
test.sdf at ±3.0
sigma and writes the data to test_clip.sdf. Notes:
The $KAPPA_DIR environment variable must
point to the location of the
Kappa binaries (this is usually done during a Starlink login).
