QDRAW

Draw a data set with plus or minus 5 sigma range

Description:

This program uses Kappa routines to calculate mean and standard deviation of an NDF. It then uses linplot to display the data with a range of plus or minus 5 sigma. Optionally, drawsig can be used to overlay 3 sigma lines.

Usage:

qdraw [-noline] NDF [Linplot/Stats/Drawsig parameters]

Parameters:

-noline
A Unix-type switch which controls whether the 3 sigma lines are displayed or not.
NDF (Given)
The required dataset
ADAM parameters = Any
Any parameters accepted by the individual routines as long as they use PARAM=VALUE format.

Examples:

qdraw test
Draws test.sdf with a scale of ± 5 sigma and draws lines at ± 3 sigma.
qdraw -noline test
Same as above but without the 3 sigma lines
qdraw mode=2 test
Plot the data using ‘+’ symbols (linplot mode 2)
qdraw mode=2 sigcol=red test
Plot with ‘+’ symbols and use red lines to show the ± 3 sigma lines.

Notes:

The $KAPPA_DIR environment variable must point to the location of the KAPPA binaries (this is usually done during a Starlink login).
