Hi, Karen this must be an misunderstanding.

The problem has nothing todo with 1D fits files.

The Problem is based solely in the source code of ij/aij.

Arbitrary 2D Fitsfiles produces the "integer fixed format Error"  (Nasa FITS File Verifier).

This is because this to lines in FITS_Write are not right implemented:

orginal file:
appendFile(writeCard("NAXIS1", " "+ip.getWidth(), "length of data axis 1"), path);
appendFile(writeCard("NAXIS2", " "+ip.getHeight(), "length of data axis 2"), path);

e.g:

Fitsformat requird a fixed valued length.
but  " "+ip.getWidth() will give variable lengths, depending on the choosen 2D fits file width!

ps: by the way - my 1d fits file plugin works perfect
