multistack

Averages groups of spectra extracted from a three-dimensional IFU NDF and then plots these averaged spectra in a stack

Description:

This shell script reads a three-dimensional IFU NDF as input and presents you with a white-light image of the cube. You can then select a number of

X

Y

positions using the cursor. The script will then group these spectra creating an average spectrum for each group. It then displays the average spectra in a ‘stack’, where each group spectrum plotted offset vertically from the previous one in the stack.

Usage:

multistack [-g number] [-i filename] [-n number] [-o number] [-z/+z]

Command-line Arguments

-g number
The number of spectra in a group.
-ifilename
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.
-nnumber
The number of groups to extract.
-onumber
Offset between the spectra in the stack.
-z
The script will automatically prompt 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.
