[Hps-analysis] FW: MC production

[dupre]

Takashi,

I do not see any 1.5mm data in your project. If we want to finalize the 
analysis of 2015 1.5mm data, it will be necessary. I would advocate that 
it is not a lot of data needed there, we only need it to evaluate the 
radiative fraction there is no background studies, but we would need it 
in a timely manner.

Best,
