Number of events in results file vs weighted events file
I want to be sure I understand the meaning of the "Events (K)" column in the results webpage.
I have some process for which I request 100k events. After generation the results webpage tells me that 2495k events were generated. The "Unwgt" column reads about 141k. These are unweighted events from which 100k were stored in unweighted_
I know that as of version 2.4.3, the events.lhe is no longer saved, and I know that you do not support older versions. However, I ran this process in version 2.4.2 just to see what the old events.lhe would have contained. I am only asking this as a question of principle, so that I understand what is happening in the MadGraph unweighting procedure. The events.lhe file contains 181k events.
My understanding was that events.lhe contained unweighted events, but yet the number of events in that file and the number of events reported in the results webpage are different by more than an order of magnitude.
May I ask what these numbers mean? I feel that this is a very basic question, but I can't find any mention of it on the help pages or any documentation. I apologize in advance if this is a trivial question.
