Slicing in DS9ΒΆ
Note
This feature is experimental and does not work with all versions of DS9 at this point.
There is a python command-line script that will be installed into your path
along with pvextractor
. You can invoke it from the command line, but the
preferred approach is to load the
tool into DS9. First, determine the path to ds9_pvextract.ans
;
it is in the scripts
subdirectory of the source code. Then start
up DS9 with the analysis tool loaded
ds9 -analysis load /path/to/pvextractor/scripts/ds9_pvextract.ans &
Then load any cube in DS9. You can draw a line, a vector, or a “segment”; only the first one drawn will have any effect. To extract the PV diagram, press the ‘x’ key or click “PV Extractor” in the analysis menu. Be patient - especially for big cubes, it may take a little while, and there is no progress bar.
