Description
I was wondering what the motivation is for sending single particles to Delphes within the DelphesPythia8 module with the log distribution given in DelphesPythia8.cpp:
pMin = 0.1 GeV for single particles
pp = pow(10, - 1.0 + (log10(pMax) + 1.0) * rndm.flat());
If anyone could provide me with some physical intuition that would be great.

Thanks pavel. Is there any particular reason why this distribution is selected over any other?

If I'm not mistaken, the idea is to obtain a flat pseudo-rapidity distribution and a flat log(pt) distribution.
