I'll slam together a residual version and add it to the page.
One option for the full redshift range is to play the same game that I
played with Figure 5-- show the full redshift range, and then an inset
with the 0.05 binning.
(Note that the binning was done slightly strangely-- I didn't just
bin at regular 0.05 intervals, but rather found a supernova, binned
whose z was no more than 0.05 above that supernova's z (with
variance-weighted combination), and then found the next highest z
supernova. Repeat. That's a slightly odd way to do it, but does reduce
the incidence of "orphans" in the case of smaller bin steps. In any
event, the plotted points are still meaningful-- although as Don would
remind us, they're only good for plotting purposes, and not what you'd
want to do an actual fit to.)
