Unix users of TUI must be careful about updating pyfits, as I just discovered. If you are using TUI 1.3 and you install pyfits 1.1 (which is required to run TUI 1.4 prerelease) then you must define the following environment variable before running TUI 1.3: NUMERIX = numarray otherwise TUI 1.3 will not display slitviewer images. I strongly recommend that you define this environment variable as part of starting up TUI 1.3. It must NOT be defined to run TUI 1.4 -- or must be set to numpy. I have fixed the tui at UW (in /net/tui). Also UW users should note that the prerelease 1.4 is available by typing "tuibeta". -- Russell APO APO APO APO APO Apache Point Observatory 3.5m APO APO APO APO APO This is message 1040 in the apo35-general archive.
