Hi Ric,

I would still like to have all the true bsg decays written out in the
cocktail. As far as I can see it, this is the most straightforward way to
study photon efficiencies as a function of energy and correct for possible
biases in a _consistent framework_, without having to start some
patchworking. I think we learned from the hadr. mass moment analysis that
this needs to be done.
>From an earlier email I remember that 'filtering on the truth block
requires little more work but is technically feasible'.

I realise that it takes longer to run over all cocktail events as the
Breco candidate needs to be reconstructed but suppose that that was also
the case in the summer 2002 production.
Then, it took me (alone) 1 or 2 days to run over all the available
cocktail, ~3.5M events, so this shouldn't delay the production much.

Cheers,
Henning
