Eric Bellm: can you please read through and comment on sections 3.1, 3.2, 3.6, 3.7? You can read other parts of the document if you like, but those are the sections that I have made the most changes to, in comparison with Pierre Astier's original text. In particular, I'd like to know if my mathematics is clear and self-consistent, and if my derivation is relatively clear. You should be able to build it by running pdflatex jointcal.tex twice (to get all references). Let me know if compiling it gives you trouble.
Pierre Astier: I've significantly re-worked the derivations and redefined some of the notation, in order to ensure we weren't overloading any letters. Any comments or suggestions you have about the above sections would be welcome, particularly if I mis-interpreted any of the notation or text.
