[Color_transp] New kinematics

Hi All,

I was scaling my table https://docs.google.com/spreadsheets/d/1R3pbuDNsrS3M-SAq8H1cNxVUEVzxr4vKOxGhfE1ATqA/edit?usp=sharing very rough, to the new Q2 points. I saw in  the run plan, that was already updated, and I would guess, more accurate than just linear interpolation, when the dependence is not linear (I just plotted them to observe the shape).

I also updated the kinematic table in the run plan, and comparing with Sebouh's, both scripts behave similar, except for 8.5 which it differs, unless, t=-0.48 (in my case). It is just an anecdote, I trust in Sebouh's script better than mine.

The only question I have about the new table is if the uncertainty is based in the new run times, original or with the extras. When I was calculating the numbers, in order to achieve the uncertainty in the proposal, should be considered only the original time, and not the extras (like 2 and not 2x3 for 1H or 2.5 and not 2.5+6 for 12C).

Then is the 20% extra suggested by Dipangkar... I forgot, but that 20% is extra data taking to compensate multi-pions isn't it? How affects the total run numbers? (time, events)

Cheers
-Carlos
