squash - Extracts a two-dimensional white-light image from a three-dimensional IFU NDF.

Description:
This shell script reads a three-dimensional IFU NDF as input and allows you to extract a specific spectral range from the cube to form a white-light image.
Usage:
squash [-i filename] [-l number] [-o filename] [-p] [-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.

  • -o filename
    The filename for the output white-light or passband image. By default the script will prompt for the name of the output file.

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

  • -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.
