Second column data in SAF output file at NLO

Asked by Hantian Zhang on 2017-08-07

What is the meaning of the second column data in the SAF output file at NLO computation? For LO computation, the SAF file's second column are always zeros in each bin, but for NLO computation, they are non-zero, and I want to know what are they. Thank you very much!

Hi,

The first column is connected to the positive-weighted events, and the second one to the negative-weighted events.

Cheers,

Benjamin
