step - Steps through the each $X$-$Y$ plane of a three-dimensional IFU NDF in the spectral direction using KAPPA:DISPLAY to display the output.

Description:

This shell script reads a three-dimensional IFU NDF as input and allows you to step through the datacube in the spectral direction in slices. The output goes to files and (optionally) to the screen.

Usage:

step [-i filename] [-l number] [-p] [-s number] [-u number]

Command-line Arguments

• -i filename
  The script will use this as its input file, the specified file should be a three-dimensional NDF. By default the script will prompt for the input file.

• -l number
  Lower spectral-axis bound of the region of interest.

• -p
  The script will plot the extracted images to the current display as well as saving it to an NDF file. [FALSE]

• -s number
  Spectral-axis step size for each passband chunk.

• -u number
  Upper spectral-axis bound of the region of interest.

Implementation Status:

This script invokes a collection of A-tasks from the KAPPA package.
