The 64-bit xgterm from the last version does not work well with igi - the

shows bad coordinates (the C-key as well).

The same situation is with the "fitpar". This makes impossible interactive analysis of data.

A graphics WCS structure was changed in the 64-bit port and this is (assuming we're talking about the same thing) due to an incompatibility between the 32-bit IGI and the 64-bit CL binary which does the graphics. The workaround is to instead use a 32-bit CL binary. If you have v2.16 Linux you can get a 32-bit binary from

ftp://iraf.noao.edu/pub/vocl.e.LNUX

Just download in binary mode, make executable and replace your existing $iraf/bin.linux64/vocl.e If you installed the 'iraf-linux.tar.gz' combined distrbution then you can copy the binary from the $iraf/bin.linux directory already on your machine.




You shouldn't be seeing this if you're running the latest v2.16.1. What platform and iraf version is this, and which keystroke were you trying to use?

This is 2.16.1 on the 64-bit Ubuntu 12.04 LTS. The problem was with deleting bad points [D] at the fitpar task.

Anyway, your workaround works perfectly in two cases: igi and fitpar run OK. Thank you.

I was happy going on with the workaround done above until I arrived to make the ccmap task. The cursor (red lines) on the CCMAP fitting irafterm have wrong x,y positions by pressing C; the delete of a particular star is not possible, because the wrong star is chosen and deleted. So the situation is similar to igi.

Are you saying the 32bit CL workaround does NOT work for this task?

YES, the workaround does not work with ccmap - I am really surprised.

I have tested the latest IRAF 32 bit version and the ccmap works without any problem with [C] and interactive fitting. The same 64 bit IRAF version does not.

I'm not able to reproduce the CCMAP problem on either Linux or OSX systems. Both the 'd' key to delete a star and the 'C' keystroke to print the coords work as expected. All I did to test was follow Example 1 from the ccmap help page, can you confirm that also fails for you? Does restarting your XGterm change anything? Did you resize the graphics window and if so, did that "break" things?

I did:

And I am able to delete with [d] but wrong points because the [C] shows bad x,y coordinates.
Anyway the igi works fine!

If I run exact IRAF 32-bit or 64-bit there is NO problem with ccmap.

On 64-bit there is a problem with IGI: [C] shows incorrect coordinates.

So I replaced - on the 64-bit Linux - the "vocl.e" as a work around you have suggested and on this configuration I can run IGI without any problem, and the ccmap has no the same problem: [C] shows incorrect coordinates.
