I use a cl script that uses wcslab in IGI to put AR and DEC grids on an image. It works fine at previous versions of IRAF. But in IRAF 2.15 (with or without patches) the DEC grid has a weird spacing... it seems to be spaced in a log scale. (I can send the old and new resulting ps files that illustrates this behavior).
I have checked the stdplot.axispar.logy parameter and it is set as no.
Moreover, if I use wcslab to put grid on image displayed on the DS9, everything works fine.
BTW, I am using IRAF32bits, since I cannot run IGI on the 64bits version.
Do you have any idea of what can be the cause of such problem?
To rule out any parameter settings, you can do a MKIRAF in someplace like /tmp or do a MKIRAF to reinitialize your uparm directory, but note that the 'axispar' pset isn't used by IGI (but 'wlpars' is). Otherwise, are you using the WCSLAB command in IGI itself, or the iraf WCSLAB task from within a CL script that also uses igi? Similarly, is your DS9 test using the WCSLAB task in IRAF or an IGI script?
In v2.15 the STSDAS/TABLES packages are unchanged from what is distributed by STSCI so if you could isolate the problem specifically to IGI then you might also ask at the ST help desk (firstname.lastname@example.org). If this is a problem with the WCSLAB task in the IMAGES.TV package then could you post an example command that produces the problem? Does initializing the uparm parameters help?
I have initialized a new IRAF environment and the problem persists...
I have the problem when I use wcslab in IGI itself. The DS9 test has been done using the WCSLAB IRAF task. So I conclude that the problem may be related to IGI... I will study a bit more the IGI pages and then, if I could not find anything helpful, I will contact the ST help desk.
