Hi all, at the very bottom of the webpage: http://www.slac.stanford.edu/~asarti/recoil/sys/theor_sys.html you can find a table with the systematics for the various theoretical changes that I was asked to do: mb,a,BRBR and excl BR. The two last ones (BRBR and excl BR.) have been done and tested while the Mb and a one still needs some understanding (comes out too small: I need to understand why). The larger sys is now that one coming from excl BR. variations (~9-10%). I hope to give you all the correct numbers before sunday morning slac time but this will be hard.... Stay tuned.
