Byte-swapped table
Guest wrote on Mar 05, 2010
Hi,
I’m revisiting some older data (circa 2006; see attachment) and when I try to TPRINT the tables, I get the following message:
            Warning: Table `n473Ha' does not exist or cannot be opened.
When I recreate the table (via ELLIPSE task in this case), it can read the table just fine. So something has changed in IRAF between 2006 and now such that I can’t read any older tables. How can I correct this problem (without having to rerun the ellipse fitting tasks)?
Thanks for any help.

Most likely, the machine used to create the original table file is not the same as the machine now being used to read it. TABLES files have always been machine dependent and subject to byte-swap issues, you'll need to either recreate the files or else find a machine with the same byte order as the original to read and convert (e.g. to a FITS table).
