hello
I have just installed IRAF with sucked on my PC, I find that it is a program very rich in application and who is very useful for my work.  Nevertheless I encounter some problems which I would like that you help me to solve them PLEASE:
 1-  I downloaded DS9 to visualize images, but I do not arrive at launching the application from the language of iraf "Cl".  For example, when I try to trace contours on images, that does not give anything on DS9. 
2-  And I can't install GRASP, although I have the packages of GRASP.

In waiting of a favorable answer,  approve  my sincere best greetings.

PS:  my PC has an operating system RedHat 9.0

Hi Aksouh,
Sorry for the slow reply.

DS9 is not an IRAF task and must be started manually before you
use the display (e.g. either on the commandline before you type 'cl'
or from within IRAF using "cl> !ds9 &" to run it in the background).
Once the DS9 is running you should be able to display images, however
overlaying graphics requires a special device name be specified. See
the CONTOUR task help page example, but briefly you can use something like

cl> display dev$pix 1 fill+
cl> contour dev$pix fill+ perim- dev=imd

will display the standard test image and overlay a contour.

> 2- And I can't install GRASP, although I have the packages of GRASP.

GRASP is the GONG external package and like all packages needs to
be declared in the $iraf/unix/hlib/extern.pkg file using something like

reset grasp = /shared/iraf/extern/grasp/
task grasp.pkg = grasp$grasp.cl

To use the package you must first load it by typing "grasp" at the cl
prompt. I believe that GRASP may still be tied to IRAF V2.11 and it may
not work under V2.12, but you'll need to contact the GRASP package authors
about that.
Note there is a similar package called GASP in STSDAS, is this
what you were referring to? Hope this helps.

Regards,
Mike Fitzpatrick
