Quoting from the description of the "Save marked files as ..." output 
file from the Athena manual (see 

    The output file will contain the x-axis value (i.e. energy, k, R, or
    q) in the first column. The remaining columns will contain each of
    the marked data groups, in the order they appear in the group list.

While Athena may not be doing whatever you think should be done, it is, 
in fact, behaving exactly as described in the user manual.  The first 
column of your "marked.xmu" file is energy, the subsequent columns are 
the set of marked groups.  In this case, you marked a single group, thus 
there is one more column, total of 2.

All that said, there is a mistake in the XDI content of the header.  The 
"Column.N" lines are generated incorrectly.  Thank you for bringing that 
to my attention.
