gridspec

Averages groups of neighbouring spectra of a three-dimensional IFU NDF and then plots these averaged spectra in a grid

Description:

This shell script reads a three-dimensional IFU NDF as input and if you request zooming the script presents you with a white-light image of the cube. You can then select the lower and upper spatial limits to plot using the cursor. You can instead supply an NDF section with the filename to define both spatial and spectral limits to plot.

The script averages spectra in the chosen region by specified compression factors in the spatial domain. It then displays the average spectra in a grid, where the exterior axes indicate the spatial co-ordinates of the averaged spectra, and the interior axes the data values against spectra co-ordinates.

Usage:

gridspec [-b string] [-i filename] [-z/+z]

Command-line Arguments

Notes:

Implementation Status:

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