Hi All. Regarding the RR ceria. The analysis carried out by us and discussed in Armstrong et al (2004a,b) did not assume a lognormal distribution, but tested the distribution model. The results from the Bayesian/MaxEnt methods, were free of any distribution function. Additional analysis showed that a lognormal distribution function fitted the Bayesian/MaxEnt results reasonable well.
