RE: Particle physics @ utopian-io - Objects isolation, histogramming and a first task request

in #utopian-io6 years ago

Hi, sorry if this is strange question but I don't understand the resulting bin data values in the SAF file.

I thought that in the histogram the bin value should be whole numbers representing the number of particles matching a particular value range.

Am I wrong about this?

Apologies for a very late answer... Complicated times for me at the moment...

I thought that in the histogram the bin value should be whole numbers representing the number of particles matching a particular value range.

It depends what you want to plot.

If you are interested in the transverse momentum distribution of all jets, then each jet of the event will contribute to the histogram (to potentially different bins). On the other hand, you may be interested in the transverse momentum distribution of the leading (or first jet) of the events. Then, only the first jet matters and will yield an entry in the histogram.

We can also be interested in plotting global variables, like the total activity in the events, which do not depend on the actual number of particle but instead of the sum of their energy.

Does it clarify?

Thanks, yes I think that clarifies it.
I will submit corrections shortly, probably today.
Cheers!

Cool! Good luck with this!
