So I tried to drag 'Tail Factor' and 'Resolution USP' under 'Peak' into report. The names showed up, but the values did not. Then I found the Extended Performance Report including those two values, I tried a second time. The values did not show up neither (shown in the picture attached below). WebApr 12, 2002 · The asymmetry factor is defined as (7) χ= t m −t 0 μ 1 −t 0 where t m is the location of peak maximum, μ 1 is the first moment (mean) of the peak, and t 0 is the hold-up time. The asymmetry factor is unity when the peak maximum position is identical to the first moment of the peak, and zero when t m =t 0. hyper arpl
