delphes_card.dat neutralino missing energy

Hi Kiel, (cc delphes author)

I've no idea about that but I guess that you are right.
In fact, we use the default card present in the Delphes program.
So I put the Delphes author in cc such that they can do this modification.

as soon as they did, doing "install Delphes" will replace the default cards.

Thanks a lot for the information,

Olivier

PS For the Delphes author:
In principle you need to add all neutralino not just the LSP.

Yes, it's correct to include "add EnergyFraction {1000022} {0.0 0.0}" in the Calorimeter configuration.

We'll add this modification to the next Delphes release including other neutralinos:

1000022
1000023
1000025
1000035
1000045

Great, thanks!
