Hi Rob,
What about making the plot linear in z, that is, x = z, not z = log(z)?
Also, I still like to see the residuals plot too.
One thing to keep in mind is that when Adam shows his residual plot
wrt an empty universe he then points to the "turn over" at high
redshift. This might be an argument for extending the residual plot
a little past 1 so the turn-over is apparent.
Sorry for the remote kibitzing on your graphsmanship!
