iraf.net

Hello! Today I configured Iraf to use of FITS directly ( V2.12.2a-EXPORT on Debian linux). Seems all work fine except for displaying and plotting of data. DS9 display just a one central line of frame. Implot command plots this line too and I can't view any columns pressing "c". What is right way to do this? Thanks.
PS. Sorry for my English.

Cheers, Eugene.

You should always be able to use FITS images directly, what did you do to 'configure' iraf to do this? If you're only seeing one line of the image then either the display frame buffer you're using is only 1-D (e.g. 1024x1) or your image only has one row. Please post a header of the image (e.g. "cl> imhead myimage.fits long+") and the frame buffer you're using (e.g. "cl> show stdimage").-Mike

Hi! I found that some other files are displayed correct. So, I think that problem is in fits headers.
Here is header of the "wrong" file:

In first case IRAF "think" that image is 1d while it is 2-dimensional. Such "incorrect" images work fine after transformation to standard .imh format.I configured IRAF to use FITS as default format changing variables imtype and imextn:
[code:1:e8da1b8ed0]
set imtype = "fits"
set imextn = "oif:imh fxf:fits,fit,mt,fts plf:pl qpf:qp stf:hhh,??h"[/code:1:e8da1b8ed0]
