Problem usung Splot to analyze a FITS fite

Khary Richardson wrote on Jul 19, 2011

Hi,
When I try to use splot to analyze a fits file I get a weird output of numbers and letters. I think I maybe missing something to properly display the FITS image. Any help would be greatly appreciated. Thanks

It means you're not actually using an XGterm window to run iraf. If you're using an XTerm then you can do a MKIRAF and change the terminal type, or do

cl> stty xtermjh ; gflush


on the commandline to change it. Terminals like rxvt, gnome-terminal, Terminal.app, etc do not support graphics and cannot be used for plots.

Hi Fitz,

thanks for the reply. When I did the install I remember setting up an xgterm
doing

Initialize uparm? (y|n): y
Terminal types: xgterm,xterm,gterm,vt640,vt100,etc.


And typing xgtermc

Can I go back and redo it?

This is from login.cl in the IRAF directory

set	home		= "/home/student/IRAF/"
set	imdir		= "/home/iraf/imdirs/student/"
set	uparm		= "home$uparm/"
set	userid		= "student"

You can do a MKIRAF and reset the default terminal type at any time, this just recreates the login.cl file. Keep in mind however, this does NOT install xgterm for you or cause one to be started, it is simply your way of telling IRAF that you have logged in using an XGterm teminal window, but installing xgterm on your machine and starting it are up to you.

Fitz,

Tried the above and got the same out put.

You can do a MKIRAF and reset the default terminal type at any time, this just recreates the login.cl file. Keep in mind however, this does NOT install xgterm for you or cause one to be started, it is simply your way of telling
IRAF that you have logged in using an XGterm teminal window, but installing xgterm on your machine and starting it are up to you.


Oh so I may not have XGterm installed? Thanks for that clarification I will check to see if I have it. If not should I install it in the iraf directory?

Normally it would be installed in /usr/local/bin, you can get it from the X11IRAF distribution for your platform from ftp://iraf.noao.edu/iraf/x11iraf.

In the meantime, an XTerm should already be installed on your machine, you'll just need to reset the terminal type and login to iraf from the xterm window.

Fitz,

Did it by doing the following to start an XGterm

 cd /home/student/IRAF
student@ubuntu:~/IRAF$ xgterm &


Which opened another terminal. I then logged in using cl. I then changed directories to the directory containing the fits files which were then analyzed.

Is there anyway of having the Xterm automatically start when one starts iraf?

Again than you for your help!!

Not really, since the point is that you start iraf from within the xterm/xgterm window they need to be running first. You can however do

xterm -e cl


(or with 'xgterm') and have the xterm/xgterm window startup IRAF for you (assuming you do this from a directory with a login.cl file).[/quote]

Okay got it. Do you know of a good tutorial for Xgterm? Wanted to know because I tried to move to different lines in the Xterm, but was unable to.
thanks again

There's no specific tutorial, but whatever you find for Xterm will generally apply to XGterm as well. If by 'move lines' you mean cut-n-paste, then use the left and middle mouse keys respectively.
