Hi,

I agree with David.

To do this, John provides also the make_hi_grid function:
   isis> c.bin_hi = make_hi_grid(c.bin_lo);

Cheers,

Manfred

make_hi_grid

  SYNOPSIS
     Use a single grid array to define a histogram grid

  USAGE
     hi[] = make_hi_grid (lo[]);

  DESCRIPTION
     Given a grid which provides the lower bin edges of a histogram
     grid, the high edges are defined as

        hi[[i:n-1]] = [ lo[[1:n-1]], 2*lo[n-1] - lo[n-2] ];

     so that the last two bins have the same width.
