tfinder

I'm trying to run tfinder on image "gFIELDc2.fits" with an catalog of stars "gFIELDc2.tab", which I created with the mkgsctab. The .tab file looks okay when viewed tprint, but I get the following dialog when I attempt to run tfinder:

tobsolete> mkgsctab 
Input coordinate list (RA Dec [ID]) (edo_usnob): 
Output GSC format table (gFIELDc2): 
tobsolete> tfinder
Image name (gFIELDc2.fits): 
Catalog table gFIELDc2.tab exists, overwrite the file? (no):

By the way, I checked the permissions for the .tab file. It should be able to be opened. Also, during this process IRAF deletes the .tab file I had created.

Any suggestions? Thanks.

At the point of the error message in the TFINDER script, the input table is renamed to a temp name, something like tmp$tmprawNNNN.tab This temp name is passed to TFIELDS as the input name and the original name is again used as the output.

You should normally see the 'tmprawNNNN.tab' files still in the /tmp directory, are they still there? Do you have permission to write to the tmp$ and current directory?

Otherwise, what platform is this on? My suspicion is that the MKGSCTAB is e.g. writing a table that is byte-swapped for the platform. Would you mind uploading the gFIELDc3.tab file to the anonftp at ftp://iraf.noao.edu/pub?

I put gFIELDc2.tab in that directory. I'm running this on Mac OS X 10.5.8.

I looked around but I cannot find the temp files.

Thanks.
