Hi Chris, Xavier,

Can you elaborate on this point? Does it mean one will have to always
feed Z->ee and Z->mumu simultaneously into this analysis? This might
not be the most practical considering that other analyses typically
only use one flavour and would thus suffer from reduced statistics if
used in the same run.

Cheers,
Frank
