iraf doesn’t display enough lines
mohack wrote on Dec 05, 2007
When i display a long image header (maybe about 100 or more lines), iraf only displays the last, let's say, 80 lines, so I don't see the top of the header when I scroll up. I solved the problem by writing the header into a file and viewing that with an editor by 'imhead x.fits l+ > header.txt'
But there has to be a way to fix that, right?
I'm using the ecl in an xgterm.

IMHEAD outputs all the lines in a header and doesn't do any terminal interaction. If you lose lines scrolling up, it's because the number of lines being saved by your terminal is too small. Try something like
when starting a XTerm to save 1024 lines for scrolling (works for XGTerm as well). The default value is something like 64 but you can reset the 'saveLines' resource for xterm/xgterm to make a more permanent change.

% xterm -sl 1024when starting a XTerm to save 1024 lines for scrolling (works for XGTerm as well). The default value is something like 64 but you can reset the 'saveLines' resource for xterm/xgterm to make a more permanent change.

You use the '-sl' option when starting the xgterm window from the unix command line, or if you start these automatically from a .xinitrc file. You can set the X resource 'saveLines' a number of places depending on your X setup, a line such as
in your .Xdefaults file.

*VT100*saveLines: 1024in your .Xdefaults file.
