Hi Rob, 

Do you have control over the input grids?  You get this message if
there are overlapping bins:


isis> c.bin_lo = [1,2,3,4,5];
isis> c.bin_hi = [1.9,3,4,5,6];
isis> c.value=c.bin_lo;
isis> c.err=c.value;
isis> define_counts( c);
Error: gap in grid at bin 1
 => set Remove_Spectrum_Gaps=1 to read it anyway
Invalid: bad grid
-1
isis> Remove_Spectrum_Gaps=1;
isis> define_counts( c);
removed 1 gaps from input grid
4


If I instead define the high grid from the low grid and append the
last point explicitly,

isis> c.bin_lo = [1,2,3,4,5];
isis> c.bin_hi = [c.bin_lo[[1:]], c.bin_lo[-1]+1] ;

there will be no error (or warning).

You can also get numerical precision errors if you try to do something
like:

isis> c.bin_hi = c.bin_lo + delta ; 


So I would suggest forming proper grids if you can.  

Hope that helps,
