Hello
While I use psf interactively , after selecting sources and pressing keystroke "a", suddenly it stopps and return me this error :

do you have any clue ?best,nakisa

If the image display (DS9 or XImtool) crashes and goes away then this is a bug in the display server, the error messages you see are because the task can no longer talk to it. OTOH, it could be a bug in PyRAF, does the same thing happen when you use the standard CL? You might get a response to PyRAF issues here, otherwise you should contact the STScI Help Desk (help@stsci.edu). There are no known open issues with the PSF task, and the error messages don't indicate it was the PSF task that failed.-Mike

hi , my error was I didn't open ds9 beside pyraf !
but now , as far I press f keystroke it works fine .but when I press r to reivew and w and q , it is not working ! do you know why ?Fitting function gauss norm scatter: 0.1013103Analytic PSF fit
Function: gauss X: 30. Y: 30. Height: 0.4287449 Psfmag: 24.276
Par1: 0.969137 Par2: 1.13536Computed 1 lookup table(s)no keystroke works after this lines ! thanks nakisa

You may need to get a newer version of DS9: during various releases things broke and some keystrokes aren't being passed through to the client in cursor-read mode (i.e. the 'f' is the builtin DS9 command not the task keystroke). You should see a blinking circle cursor when in cursor mode, if IRAF and DS9 somehow lost sync in the read then you can try to restart DS9. I'm also assuming this isn't an input-focus problem, i.e. do you need to click on the DS9 window to direct input to the window or does the focus follow your mouse?

Hi I think the connection between ds9 and pyraf is lost :

What is your suggestion ?
Best,Nakisa

It looks like the DS9 died, did the window disappear? If so then this is a problem in DS9 and not the task. Various versions have been known to have problems with image display, try getting the latest version from SAO or checking the DS9 web pages for known problems.

hello
I check ds9 's version is 6.0 . so the problem is not the version!best,nakisa
