stacker - Plots a stack of spectra extracted from a three-dimensional IFU NDF.

Description:

This shell script reads a three-dimensional IFU NDF datacube as input and presents you with a white-light image of the cube. You can then select a number of $X$-$Y$ position using the cursor. The script will then extract and display these spectra in a `stack' with each spectrum plotted offset vertically from the previous one in the stack.

Usage:

stacker [-i filename] [-n number] [-o number] [-z/+z]

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.

• -n number
  Number of spectra to extract.

• -o number
  Offset between the spectra in the stack.

• -z
  The script will automatically prompt the user to select a region to zoom before prompting for the region of interest. [TRUE]
  +z
  The program will not prompt for a zoom before requesting the region of interest. [FALSE]

Implementation Status:

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