Previous: gridspec - Averages groups of neighbouring spectra of a three-dimensional IFU NDF and then plots these averaged spectra in a
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
-
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.
- -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
The number of groups to extract.
- -o number
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.
