While inclusion of a Figure 4 is not essential for the purpose of illuminating the statistical flaws in the Douglass et al. "consistency test", such a Figure would clearly show the (currently large) structural uncertainties in radiosonde-based estimates of the vertical profile of atmospheric temperature changes.

I'm perfectly happy to include a version of Figure 4 in our response to Douglass et al. If we do go with inclusion of a Figure 4, you, Peter, Dian, Melissa, Steve Sherwood and John should decide whether you feel comfortable providing radiosonde data for such a Figure.
