Additional Info |
Note for IRAF users:
"Due to the unique relationship between DS9 and IRAF, if you use the imexamine
task, you can take advantage of a special feature of DS9. Instead of loading the image from
IRAF with the display task, load the image directly into DS9.
Then, from the cl prompt, invoke imexamine
without a filename. IRAF will ask DS9 for the current filename and use it for analysis.
This approach provides serveral advantages over previous methods. First, it will work with
compound fits images such as mosaics, data cubes, and rgb images. Second, the image display
includes true image data and WCS information, not the approximated data from IRAF." |
